If you wish to +maintain your welcome on whatever system you happen to call, it would be to your +advantage to observe these few rules. + + 1. Don't habitually hang up on a system. Every Sysop is aware that +accidental disconnections happen once in a while but we do tend to get annoyed +with people who hang up every single time they call because they are either too +lazy to terminate properly or they labor under the mistaken assumption that the +10 seconds they save online is going to significantly alter their phone bill. +"Call Waiting" is not an acceptable excuse for long. If you have it and intend +to use the line to call BBS systems, you should either have it disconnected or +find some other way to circumvent it. + + 2. Don't do dumb things like leave yourself a message that says "Just testing +to see if this thing works". Where do you think all those other messages came +from if it didn't work? Also, don't leave whiney messages that say "Please +leave me a message". If ever there was a person to ignore, it's the one who +begs someone to leave him a message. If you want to get messages, start by +reading the ones that are already online and getting involved in the +conversations that exist. + + 3. Don't use the local equivalent of a chat command unless you really have +some clear cut notion of what you want to say and why. Almost any Sysop is more +than happy to answer questions or offer help concerning his system. +Unfortunately, because about 85% of the people who call want to chat and about +99% of those people have absolutely nothing to say besides "How old are you?" or +something equally irrelevent, fewer Sysops even bother answering their pagers +every day. + + 4. When you are offered a place to leave comments when exiting a system, +don't try to use this area to ask the Sysop questions. It is very rude to the +other callers to expect the Sysop to carry on a half visible conversation with +someone. If you have a question or statement to make and expect the Sysop to +respond to it, it should always be made in the section where all the other +messages are kept. This allows the Sysop to help many people with the same +problem with the least amount of effort on his part. + + 5. Before you log on with your favorite psuedonym, make sure that handles are +allowed. Most Sysops don't want people using handles on the system. There is +not enough room for them, they get silly games of one-upmanship started, it is +much nicer to deal with a person on a personal basis, and last but not least, +everyone should be willing to take full responsibility for his actions or +comments instead of slinging mud from behind a phoney name. + + Also when signing on, why not sign on just like you would introduce yourself +in your own society? How many of you usually introduce yourselves as Joe W +Smutz the 3rd or 4th? + + 6. Take the time to log on properly. There is no such place as RIV, HB, ANA +or any of a thousand other abbreviations people use instead of their proper +city. You may think that everyone knows what RIV is supposed to mean, but every +BBS has people calling from all around the country and I assure you that someone +from Podunk, Iowa has no idea what you're talking about. + + 7. Don't go out of your way to make rude observations like "Gee, this system +is slow". Every BBS is a tradeoff of features. You can generally assume that +if someone is running a particular brand of software, that he is either happy +with it or he'll decide to find another system he likes better. It does nobody +any good when you make comments about something that you perceive to be a flaw +when it is running the way the Sysop wants it to. Constructive criticism is +somewhat more welcome. If you have an alternative method that seems to make +good sense then run it up the flagpole. + + 8. When leaving messages, stop and ask yourself whether it is necessary to +make it private. Unless there is some particular reason that everyone shouldn't +know what you're saying, don't make it private. We don't call them PUBLIC +bulletin boards for nothing, folks. It's very irritating to other callers when +there are huge blank spots in the messages that they can't read and it stifles +interaction between callers. + + 9. If your favorite BBS has a time limit, observe it. If it doesn't, set a +limit for yourself and abide by it instead. Don't tie up a system +unnecessarily. + + 10. Have the common courtesy to pay attention to what passes in front of your +face. When a BBS displays your name and asks "Is this you?", don't say yes when +you can see perfectly well that it is mispelled. Also, don't start asking +questions about simple operation of a system until you have thouroghly read all +of the instructions that are available to you. I assure you that it isn't any +fun to answer a question for the thousandth time when the answer is prominently +displayed in the system bulletins or instructions. Use some common sense when +you ask your questions. The person who said "There's no such thing as a stupid +question" obviously never operated a BBS. + + 11. Don't be personally abusive. It doesn't matter whether you like a Sysop +or think he's a jerk. The fact remains that he has a large investment in making +his computer available, usually out of the goodness of his heart. If you don't +like a Sysop or his system, just remember that you can change the channel any +time you want. Besides, whether you are aware of it or not, if you make +yourself enough of an annoyance to any Sysop, he can take the time to trace you +down and make your life, or that of your parents, miserable. + + 12. Keep firmly in mind that you are a guest on any BBS you happen to call. +Don't think of logging on as one of your basic human rights. Every person that +has ever put a computer system online for the use of other people has spent a +lot of time and money to do so. While he doesn't expect nonstop pats on the +back, it seems reasonable that he should at least be able to expect fair +treatment from his callers. This includes following any of the rules for system +use he has laid out without grumping about it. Every Sysop has his own idea of +how he wants his system to be run. It is really none of your business why he +wants to run it the way he does. Your business is to either abide by what he +says, or call some other BBS where you feel that you can obey the rules. + + \ No newline at end of file diff --git a/textfiles.com/bbs/works.phk b/textfiles.com/bbs/works.phk new file mode 100644 index 00000000..f39fe1b6 --- /dev/null +++ b/textfiles.com/bbs/works.phk @@ -0,0 +1,175 @@ +================================================= +AN EXTREMELY IMPORTANT MESSAGE TO THE WORKS USERS +================================================= + +Hello. + +This is a message from Jason Scott, original SysOp +of The Works from 1986-1988, its genesis years. I +started The Works when I was 16, and ran it until I +went to college. Some time afterwards, an extremely +young fellow named Dave Ferret asked me if he could +try setting up the BBS at his house, and after a +little less than a year, David got his parents to pay +for a third line into the house and he put up my BBS. + +When Dave first got his hands on The Works, it was +extremely funky and weird. I had written the software +in QuickBasic, and called it Ferret BBS, after my pet +ferret which was forced to live in the same room as the +computer and constantly ringing line (I never shut it +off). The reason I was running this software was to +emulate on the PC what was one of the coolest pieces +of software on the Apple ][, that is, Waffle BBS v1.62. +I had basically tried to emulate a lot of what I found +wonderful about that software, and put some time into +my own little mods. + +Dave suffered with this software for some months, and +then the Waffle folks switched their software over to +the PC, and I urged Dave to switch to the original bbs +code which I had been trying to emulate anyway. + +It was Dave who ran the Works from 1989 to the present. +That's 6 years, three times longer than I ever ran it. +It was under Dave who got us Internet E-Mail, Dave who +supplied the electricity and hard drive space for the +system, and Dave who was the system administrator for +the Works' growth into a CdC system and world-famous BBS. + +The Works grew here in Lexington into a place where the +users would have Works Get-Togethers, in pizza places, +the Au Bon Pain, and wherever else we thought would be neat. + +Along the way, we also gained some of the more effective +administrators that any BBS would offer: Iskra and Veggie +were the two that I shared time with and they're still +among my best friends in the world. The amount of work +these two guys put in to make the Works into the system it +has become can't be discounted in the least. They knew what +people wanted, and knew what the system needed, and put in +the hours and hours to make it work. Their influence is +everywhere in this system. + +This brings us to the present. + +Now, it's 1995, the Works is nearly 10 years old and Dave +has done some soul-searching and decided he can no longer +give the system the attention he thinks it deserves. So, +he asked me to take the Works back, to put it up and run +it again like I did 7 years ago. I accepted, thinking it +wouldn't take that much of my time anyway, so it wouldn't +be a problem. Besides, I probably had an extra phone line +or two, and it wouldn't be a problem. + +I have to the conclusion that I was wrong. + +A little technical background: My theory was that I have +a Macintosh SE that I have SoftPC running on, and by +running Waffle through the SoftPC, I could run the Works +effectively. This Macintosh has been running for three weeks +now and I'd say it functions like it's supposed to about +1 out of every 3 days, and even then for a few hours +until I get over to the computer office I own to reset it. +I had an extra phone line on my hunt group and thought that +I could just stick a copy of the system on there and leave +it and everything would be just great. Again, this theory +is wrong. + +I've also done some personal soul-searching and I have +come to the conclusion that the Works in its current +incarnation should die. As much as we'd like to extend the +Works, like closing your eyes and hoping that your really +good dream will go on, I don't personally think that could +happen. I think that the two solutions that Dave presented, +the first of me taking it over, and the second, of the +l0pht taking it over, would produce a cheap, bastardized +version of the Works that the administrators would consider +an afterthought and not a primary concern. This isn't +criticizing anyone, this is simply stating that trying to +run a BBS is either a time-consuming situation, or it becomes +like the summer cabin in the woods that has all sorts of +repairs to do but you put them off until next summer to fix them. + +But because the Works has always been a product of love, and +a product that comes from my heart for reasons I won't go +into here, I am offering at least a partial solution. Hear +me out and don't press the Q key. + +Some of you know and some of you don't care that I already +run a BBS right now. This BBS is called "COWZ", or COWZ +Technologies or cow.net depending on your mood. This year, +I decided to get into the Internet Access Provider business +and have stuck something on the order of $10,000 into this +venture. It takes the majority of my free time to make it +a place worth coming to. I care very much for it, and I +think it has the potential to become a world-class venture. +I am connected to the Internet via a direct 24-hour 56kb +connection, and am cow.net and telnettable from the world +at large. + +I propose to put The Works into COWZ. + +The way that I would propose this is to put the Textfiles +that made the Works so popular in the first place into my +500-meg file system, and create message boards that Works +Users would want into the message bases, and generally do +what I can to make the Works Community welcome. + +There are two facets to this offer that I think should +be mentioned. + +The first is that it will cost money to use COWZ. Right now, +I'm selling my services, which include direct telnet and +usenet newsgroups, along with FTP, WWW via the "Lynx" +text-only browser, and of course the BBS for $75 a +year. I think this is a really good price and I also +think it's a bargain. HOWEVER, I also think that telling +Works Users that their price for using the bases and files +of the Works has gone from $0 to $75 a year would be +beyond henious, so I offer Works Users the price of $25 a year. + +To the chorus of "Fuck You"s, I would like to point out +that these Works Accounts would be full-featured COWZ +Accounts, and would contain all the services that other +users have, for 1/3rd the price. The way that you would +get this extremely special price would be to mention the +Works in a letter to my account: system@cow.net. +Arrangements can then be made. + +COWZ is running on several sun workstations, with 7 +incoming phone lines and uses Waffle UNIX Software. +It is functionally similar to the Works you have grown +used to. The main difference is that you would have +more you could do at the prompt. + +The other facet worth mentioning is that Dave doesn't know +this offer I've made. He might not approve, and might +decide to do something else with the Works than have it +die and be sucked up into COWZ. Dave is more than within +his rights to do so; he really does own the name "The Works" +as far as I'm concerned. I was 17 when I last ran the +Works; Dave ran it all through his teenage years and now +into his 20's. Dave also runs works.com and would be +more than free to give that domain to someone else, even +another BBS. Dave would have my full blessing to do so, +but I hope that he'll see what I'm trying to do and join me. + +What I hope to be proposing is a new era in the Works for +the users who grew up with the love of information +and interaction that the system stood for, an era where +the Works users have Internet on top and access to the +world from the same sneering citadel of "We're gonna give +it our best shot to make a difference and put up every +textfile known to man" that the Works always spoke from. + + The COWZ Technologies BBS is available + by calling 1-617-COW-TOWN or 617-269-8696, + or by telnetting to cow.net from your UNIX + prompt via internet. I am on COWZ as + system@cow.net or root@cow.net, and will + gladly answer all queries and questions that + you would care to throw my way. + + With much love, + Jason Scott \ No newline at end of file diff --git a/textfiles.com/bbs/workslogin.txt b/textfiles.com/bbs/workslogin.txt new file mode 100644 index 00000000..a72377aa --- /dev/null +++ b/textfiles.com/bbs/workslogin.txt @@ -0,0 +1,37 @@ + Cambridge, Summer. + + City of socialists, neighborhood of crime and credulity, den of + inequities both real and imagined.

This is a sign of the frustration we are +all feeling with zip looking as if it is dead in the water. We are +starting to wonder if perhaps a hacked version of zip and unzip might +be better than the unapproved alpha versions PKware has allowed to float +around for so long. To explain: + +PKware has set a new record in the computer industry. They have had an +alpha test version of their zip and unzip software circulating on bulletin +boards for more than a year. Typically, a company will distribute an alpha +version to selected testers, then within a reasonable amount of time will +distribute a beta version, then will soon release a real version after that. + +In late 1991 PKware distributed their PKZ193A.EXE, "A" for alpha, zip software +and it immediately appeared on every BBS in the country. Fine, alpha versions +are soon replaced by beta, then final versions. No problem. Well, here +we are, just about into 1993. The old alpha version is still causing +frustration and confusion on most bulletin boards. + +To quote a typical message received from an innocent BBS user: + +"Why does this BBS have so many files that don't work? When I unzip the file +PKUNZIP tells me "I don't know how to handle this file". You should check +your files more carefully.

The problem is PKware sitting on an alpha version and +seemming to do nothing about it. + +I propose the following: We do some research to see what other compression +software might be more appropriate for use on BBS systems, and discuss +converting all collections from zip to whatever compression techniques looks +like a logical successor to the confused zip situation. + +After all, if PKware ever attempts to release another version in the future, +we can probably look forward to at least another year of version confusion, +profane messages, extremely frustrated new users, and 30 or 40 messages +per week from people confused about the lack of any zip standards. For the +4 or 5 years we have been using zip format, one full year has been under +non-standard formats with an alpha version floating around.

+Your one-stop shop for all files of a "computery" nature, that cover how to +rebuild a piece of computer hardware to do something it was +never meant to do, or to see someone go really deeply into a computing +subject that would cause most people to yawn and look for the snack table. +Since BBSes were on computers, it was natural for people who used BBSes +to focus on all aspects of these wonderful machines. The evidence of +their interest and their experimentation resides below. +

+Of course, nearly ALL textfiles are computer-related in some fashion, and +some subjects might fit here but fit even better in another section. For +example, you should most definitely check out the +programming +and apple sections as well, as you might not agree with +what I decided should go where. +

General Computer Textfiles

+

+Your one-stop shop for all files of a "computery" nature, that cover how to +rebuild a piece of computer hardware to do something it was +never meant to do, or to see someone go really deeply into a computing +subject that would cause most people to yawn and look for the snack table. +Since BBSes were on computers, it was natural for people who used BBSes +to focus on all aspects of these wonderful machines. The evidence of +their interest and their experimentation resides below. +

+Of course, nearly ALL textfiles are computer-related in some fashion, and +some subjects might fit here but fit even better in another section. For +example, you should most definitely check out the +programming +and apple sections as well, as you might not agree with +what I decided should go where. +

The people at +Toshiba could have done a better job in a couple of respects: + + First, they did a poor job of extracting vertical sync pulses from the + video signal that comes from the Amiga. This produces an error in the + interlacing when the Amiga is used in 320x400 or 640x400 display modes. + When you look closely at the screen you see alternating line spacings. It + also gives characters a ragged look. The modification described in the + dPaintII file reduces the interlace error by a factor of about 5. + + While interlaced video isn't the nicest thing to read characters on, it's + neat to be able to put nearly all of a typewritten page on the screen. Most + of the Amiga outlets handle a neat thing called Jitter-Rid, or some such + thing. It is a thick piece of smoked plastic that goes on your 1080 + monitor. It enhances the contrast and attenuates the light from the screen + to keep your brain from rattling too badly from the flicker. Also, dark + characters on a light background seem to work best for me, anyway. + + The second problem is a thing called crossover distortion. They did a dumb + thing that distorts the audio, even at very low volume levels. The Amiga + deserves better sound. Unfortunately, this mod takes 2 diodes and a + resistor, but it essentially eliminates the crossover distortion. + + If you aren't afraid of working on the average modern TV set, the 1080 + shouldn't prove to be much of a problem. Looking from the back, there are + four screws, one at each corner. You need a long Philips screwdriver for + those. There is a bottom plate that that also needs to come off. Finally, + there is a screw just above the RGB input connector. Now, if you place the + monitor face down on a soft towel, you can, with a little judicious prying + and tugging, lift the rear part of the case off. Watch out for the speaker + lead. You will have to unplug the connector before the back can come clear + off. + + You will need to have something to support the neck of the CRT. A 1x4 about + 3-4 inches long worked pretty well. The whole assembly is pretty limber, so + use reasonable caution. The main board on the bottom can be slid back along + with all of the front-panel knobs. This permits access to the controls - you + might as well squirt some contact cleaner in there while you are at it. + + If you are looking at the bottom, with the face of the CRT on your right, + you will see a large IC that is the guts of the whole thing right in the + middle of the board. C304 is visible above and to the left of the centerline + of that humongous IC. + + The board that contains the audio output amplifier is on the left side of + the 1080 if you are facing the screen. Looking at the underside of the + board, the components you are looking for to do the audio mod are on the + upper left corner. + + Fortunately, the P.C. boards have component numbers screened on them, so it + isn't too hard to find the parts. I did the audio mod by lifting the + collector lead of Q605 out of the hole and wiring directly to it. In + retrospect, it probably would have been easier if I had just soldered an + insulated wire to it, brought the wire through the hole and done all of the + wiring on the backside of the board. If you are concerned about vibration + messing up the "air-wired" connections, a shot of hot glue or some similar + measure should put your mind at rest. The diodes are 1N914s from Radio + Shack, but most any small-signal silicon diode should do. diff --git a/textfiles.com/computers/1105.txt b/textfiles.com/computers/1105.txt new file mode 100644 index 00000000..e1700dee --- /dev/null +++ b/textfiles.com/computers/1105.txt @@ -0,0 +1,60 @@ +Document 1105 +BOOTING WITH DR DOS + +Initials: + BPT + 10/31/91 + GENERAL + +Keywords: + BOOT + INSTALL + +Description: + In order to install DR DOS you must make sure that you are + booting from a floppy in drive A:. DR DOS will not install + from drive B:. DR DOS comes on 3 1/2 inch low density + floppies and 5 1/4 inch Hi-density floppies. If you need + 5 1/4 inch low-density disks (360K) send in the coupon that + comes with your DR DOS. + + If the boot disk hangs while trying to load, usually it means + there is an incompatible or faulty piece of hardware. + + One of the things it can be is simply an older floppy + drive that is out of alignment. Sometimes the situation + can be salvaged by formatting a floppy on the boot drive + with the old DOS, then doing a diskcopy. The potential + problem is that the diskcopy may not be able to read the + boot disk either. If you can't make a backup then it may + be necessary to get a replacement disk set from Digital + Research (in case there is an actual error with the disk, + which does sometime happen) or see about getting the + drives aligned. + + ******************************************************** + + Another problem is where you can make valid Diskcopies + but all you get is the message "Loading...". Here the + potential problem may be the computer's bios. DR DOS + must be able to direct the system to the area where DOS + Kernel files are located.

If this is an XT + type computer (by which we mean it has no CMOS config- + uration program) then you can place a DRIVPARM state- + ment in your CONFIG.SYS. Refer to the DR DOS manual to + see how to use this parameter. DRIVPARM uses no RAM. It + merely updates the DR DOS drive tables with the type + drive you specify.

If you have Tos v2.06 and STE, even the TOS will recognize +that you have an 1.44 drive installed as your internal drive!!! Version 1.1 +============================================================================== + +This whole thing started a few days ago, when I decided that I was fed-up with +all those 720 Kb disks, I needed something better for backing up all the wares +from my BBS, and I thought.... Hmm, wait a sec, the Pc dudes have 1.44 drives +in their computers, and so does the Mega STE.... Why not install one in my +"normal" STE as well??? Then I started planning for the project, and came to +this conclusion: + +1. You must have a WD1772-02-02, the other ones will not handle the doubled +clock frequency of 16 mHz without problems. + +2. Your 1.44 Mb diskdrive must output a signal on pin 2 (HD detect) whenever a +HD disk is present in the drive. Examples of drives that works fine with this +modification: TEAC and Panasonic. I used a Panasonic drive for my own +computer. Not all drives have the jumpers set-up correctly when you buy them, +so *NEVER* buy a drive if they cannot tell you fer sure that it really has the +HD detect signal output. Because if it doesn't have it, you're fucked up!! + +3. You must have some kind of circuit that only enables 16 mHz when drive 0 is +selected and a HD disk is present in drive 0....... + +4. If you have a STE, you should also solder a jumper on bridge E6 underneath +the drive in order to get TOS to recognize that you have a 1.44 Mb drive. + + +The Circuit: +============ + +I designed my automatical HD detect switch around a 74LS00 and a 74F157. The +LS00 is a quadruple NAND gate, and the F157 is a dual two-to-one multiplexer. +The first thing you need to do, is to invert the HD detect signal with one of +the NAND gates, you simply feed the HD detect on both inputs of one of the +NAND gates and there you have it - inverted HD detect on the output of that +NAND gate!!!! What you do now, is that you take the drive B select signal and +the inverted HD detect signal and feed them onto the inputs of a second NAND +gate. Now, you'll only get a '0' output from the second NAND gate if.... + + * Drive B is not selected + * Drive A contains a HD disk + +After this, we simly feed the output of the second nand gate to the select +input on the F157 multiplexer.

Furthermore, + the developers felt that if you attempted to reformat the diskette + to 1.44 MB, which uses the lower write current, the 1.44 MB format + would not completely write over the "deeper" 720 KB format. + Therefore the developers' recommendation was to discard a 2.0 MB + diskette that was formatted to 720 KB. + + THE SUBSEQUENT FINDINGS + [aka a RETRACTION] + + Since the time that this caution was issued, the developers have + performed additional testing, and have concluded that there is no + need to discard a 2.0 MB diskette that was formatted to 720 KB. + + It is still true that a 2.0 MB diskette formated to 720 KB will + cause intermittent data errors.

Just be glad it works in 720k mode. :^) + +Well, you can, if you hack the hardware. + +Here we go again: + +The trick is to double the clock frequency of the controller chip, so it +will talk twice as fast to the drive: the bit stream has "high-density" +format. +A clock of 16 MHz is well beyond specification (the WD1772 is rated to +run at up to 10 MHz), but it will work most of the time. + +The hack consists of two parts: hardware and software and works with +( [3.5 inch] <- RBPIII ) high density drives only! + +[The reason being that the drive must auto-sense the HD disk when it is + inserted and change its RPMs up accordingly. 5.25 (1.2Meg) drives do + *not* do this! Neither do all HD 3.5" floppies (notably the ones on + true blue PS 2 s). ] <- RBPIII + +Now: the hardware. + +The clock pin of the WD1772 is pin 18. It is normally hooked to the 8 +MHz clock. +Cut this pin and connect it to the output of a simple circuit. feed the +two inputs of this simple circuit with 8 MHz and 16 MHz clocks (16 MHz +can be gotten at SHIFTER pin 39). +The "simple circuit" mentioned above could be a simple, manual switch. +Now You are able to select two clock frequencies and therfore two +"modes" for the controller chip: double density and high density. + +The simple circuit could also be a multiplexer (74LS157, I think) +controlled by the "I detected a HD-disk in me"-output of the floppy +drive (the TEAC FD 235 HFN provides this outout on pin 2 if a jumper is +set; the 235 HFN has a second jumper that enables internal detection of +HD disks: this must be set, too). +With the MUX, a disk inserted will select the appropriate mode of +operation automatically. + +Do not worry about two drives in different modes: when copying from one +drive to the other, the clock rate will be switched once to twice a +second. This will not trouble the controller (remember the clock to be +in the range of Megahertz...). +If you want to connect one HD drive and one DD drive, you'll need two +more TTL gates (one 74LS00 will do) to make sure, the controller is in +DD mode for the DD only drive: invert the HD-detected-output (it is LOW +for DD before, HIGH for DD behind the inverter) and feed it into a NAND +gate together with drive select for the DD drive. Let a HIGH output of the +NAND gate select DD-clock (8 MHz). Now "not-HD-detected OR DD-drive-select" +will select DD mode, right? + +With two HD drives, there is no problem at all :-) [except for the +High Density floppy boot problem, discussed below. You have to set +the step rate from the boot sector.] <- RBPIII + +Now for the software: + +The controller uses its clock as base for all timings. +The pulse width and time between pulses for the step line are controller +controlled. ^^^^^^^^^ + [WD 1772] <- RBPIII +To make it short: with the doubled clock the controller will try to make +the head step twice as fast: he will send a step pulse every 1.5 +milliseconds if set to 3 milliseconds (which is TOS standard). +Just set the step rate to 6 milliseconds to make the controller step 3 +milliseconds in HD mode (well, the 6 milliseconds steps in DD mode will +slow down floppy operation a bit, but not that much. Not stepping, [but] +reading and writing takes the time!). + +How to set the step rate? +Well, there is a documented TOS variable for the step rate at 0x440 +called seekrate. +The step rate in this variable will be used by the BIOS after a call of +the routine, pointed to by "hdv_init" (the hdv_init routine seems to +initialize the BIOS parameter blocks for the floppies). The pointer to +hdv_init can be found at 0x46A (this is a supported TOS variable, too). +Look at the MWC-Assembler source below. + +[More information on the step rate from another posting - between the +curly braces below] <- RBPIII + +{ + In article <1346@uvm-gen.UUCP> pegram@uvm-gen.UUCP (pegram r) writes: + > + >Rats! I looked up the possible seek rates last night, 6 msec is as slow + >as she goes. + + Hmm, TOS will step at 6,12,2,3 msec (with rate codes 0,1,2,3). + Setting the controller to 6 msec and doubling the clock works for almost + all 3.5 inch HD drives. + + [I wanted to know if you could still use a (360 K) 5.25 drive, which + needs a true 6 msec step rate. This was when no WD 1772 clock switching + (between 8 and 16 Mhz) was contemplated. If your 1772 works this + fast, you can forget the switch, or use a properly buffered manual + switch for those rare occasions when it's necessary. "Properly buffered" + you ask? See any of the usual designs that eliminate switch bounce - + Radio Shack's pamphlets on digital electronics have the circuits needed. + The 74LS00 mentioned above will work nicely as the debouncer and "glue". + You still want that Multiplexer and you send in the debounced 16Mhz ("On" + or "TRUE") and 8Mhz (The inverted "FALSE" or "OFF") outputs from the manual + switch to select the clocks. That is just a design off the top of my + head, which needs to be improved. Please do post a better one if you + come up with one, I can think of a one chip (the LS00) solution if + clock skew to the WD1772 is unimportant (as in 180 degrees out of + phase 8-). The reason I mention it is because, I believe that the + problem mentioned at the beginning of the original posting was due to + either an incorrect jumper setting on the drive, or a noise problem + in the ST, having the clocks going all over the ST to the switch, + is not a good idea at all!

A UART chip is the 40 pin chip on your serial prort. + UART means Universal Asynchronous Receiver Transmitter. This + chip converts an 8 bit byte from parallel to serial and from + serial to parallel. Your computer sends the byte on a PARALLEL 8 + bit bus to the serial card. The serial card has to send it + SERIALLY to the modem. And at the same time it adds a START BIT + and a STOP BIT. If you are using a 7 bit format, the UART chip + can also add the parity bit, which can be even, odd, zero, forced + to 0, or forced to 1. It can also add 2 stop bits instead of 1 + stop bit. And in the case of certain baud rates, it can add 1.5 + stop bits instead of 1 stop bit. + + Well, a problem cropped up with the HST modem. To gain the + maximum efficiency of this modem, you have to set your serial + port to 19,200 baud. Yes, that is 16 times faster than your + normal 1200 baud modem. Now most computers, even XT's, can keep + up with that. But there is a problem caused by some EXPANSION + boards like Perstor disk controllers, and Network Interface cards + (like Ethernet) that hog, or tie up, the interrupts, or IRQ's. + If the other board hogs the interrupts longer than one character + time (1/1920th of a second) then the character that is coming in + over the serial port is LOST and gone forever. With a 2400 baud + modem, you have a 1/240th of a second 'slack' between characters. + (Remember, 8 bits, plus one start bit, plus one stop bit, give + you 10 bits (not 8) when talking about modems and serial ports. + So you divide bits per second (bps) by 10 to give CHARACTERS per + second (cps). So these problems didn't crop up with modems up to + 2400 baud. But when running 9600 baud and 19200 baud, they did + show up. + + What was needed was a way to "hold" those characters until the + computer could catch up with the serial port. One way of doing + that was making an expensive INTELLIGENT serial card. You could + put some local memory on there and a small microprocessor like a + 6052 or 8088. But National Semiconducter went even better! + Instead of making the whole card smarter and a whole lot more + expensive, they put all the smarts on the UART CHIP! The new + UART chip, called the 16550, has a 16 byte FIFO buffer. FIFO + stands for "first-in-first-out". With this buffer, the computer + can be busy doing something else for up to 16 character times, + and no characters will be lost. + + The original UART used in XT computers was the 8250. This was + kind of slow, but adequate for the 4.77 Mhz bus speed of the XT. + With the 8 Mhz bus speed of the AT, a faster chip was needed so + they used the 16450. These 2 chips are functionally identical, + and are pin compatible. They have 40 pins each. Actually, you + will see many AT computers with a 8250 UART on their serial port. + + The 16550 will work on any serial port that now has an 8250 or + 16450. You just replace it. But you also need some special + software to activate the buffer. Otherwise, the 16550 will act + like a 16450 without the buffer. + + There is a program called 16550.EXE which tells the UART to turn + on the FIFO buffer, and then the UART is just transparant to + whatever communication program you are using. I have been told, + on a TELIX support conference, that Telix 3.11 has 16550 support + built in. I don't know if other popular telecom programs such as + Procomm+, Qmodem, and other have it or not. + + There was a user on a local BBS who was having problems even + downloading at 2400 baud because he was using Desqview, and + running several programs simultaneously. He installed the 16550, + and his problems went away. Another local sysop using an HST + didn't even have any of the "problem boards" mentioned later in + this article. He installed the 16550, and then was able to + consistently use 19.2K baud with no problems. His transfer + efficiency rose from 96% to 115%. + + You can obtain the new 16550a complete with new Multi COM card. + ($65.00 plus s/h) from Node 66 East BBS 914-426-0729. + + Here are some situations where you *might* benefit from a 16550 + UART while doing high speed transfers with the serial port: + + 1) You have a Perstor controller with an older ROM on it. I have + read that some rom versions take care of the IRQ hog problem. + + 2) Your computer is on any kind of network. Network interface + cards are notorious for hogging interrupts. (Tho' not all do.) + + 3) Your computer is an AT and you are using EXTENDED memory. The + AT has to do a reset and takes a lot of time to switch from + protected mode to real mode when its done with accessing + extended memory. (Tho' not all AT's have this problem.) + + 4) You are running a multi-tasking software like Desqview or + DoubleDos and are trying to do communications in the + background, and lose characters when switching windows, or + have too many background tasks/windows active at the same + time. + + 5) You are a sysop with an HST modem and are getting less than + 100% efficiency on your mail transfers. Many factors affect + this, so a 16550 *may* or *may-not* increase your efficiency + to over 100%. + + diff --git a/textfiles.com/computers/1991-12 b/textfiles.com/computers/1991-12 new file mode 100644 index 00000000..4c8c0797 --- /dev/null +++ b/textfiles.com/computers/1991-12 @@ -0,0 +1,942 @@ +From pub-infra-request Tue Dec 10 13:34:55 1991 +Received: by eff.org id AA05611 + (5.65c/IDA-1.4.4 for pub-infra-exploder@eff.org); Tue, 10 Dec 1991 18:34:57 -0500 +Reply-To: pub-infra +Precedence: bulk +To: pub-infra +Date: Tue, 10 Dec 1991 18:34:55 -0500 +Message-Id: <199112102334.AA05606@eff.org> +Subject: What is ISDN Good For? +From: mkapor (Mitch Kapor) +Sender: ckd + +habs@panix.com (Harry Shapiro) writes: + +"What applications that require ISDN can't already run with existing +products like switched 56 kbit, and 14,400 modems?" + +Switched 56 kilobit service has the same order of bandwidth as 64 kbit +ISDN, but its availability is strikingly different.

Congress + +In a letter to Mitchell Kapor from the Chairman of the Subcommittee with +primarily jurisdiction over telecommunications policy dated November 5, +1991, Representative Edward J. Markey complemented Mitchell Kapor on his +"insights on the development of a national public information +infrastructure" which "were appreciated greatly by myself and the Members +of the Subcommittee." + +Chairman Markey, writing to Mitch Kapor as a representative of the computer +industry, called for other leaders in the industry to participate more +actively in the policy process. The letter states: + +"In crafting the right policies [for the telephone network], the assistance +of you and your colleagues in the computer industry is critical if we are +to bring the benefits of advanced information technology to the American +public. As I said at the hearing, we need to pursue policies that +encourage the Bell companies to work with other sectors of the +communications industry to create a consumer-oriented, public information +network. Please let me or my staff know what policies you and others in the +computer industry believe would best serve the public interest in creating +a reasonably priced, widely available network in which competition is open +and innovation rewarded. I also want to learn what lessons from the +computer industry over the past ten to fifteen years should apply to the +current debate on structuring the information and communications networks +of the future....I ask your help in gaining input from the computer +industry so that the Subcommittee can shape policies that will bring this +spirit of innovation and entrepreneurship to the information services +industry. + +Key members on the Senate Commerce Committee have also expressed serious +interest in the proposal and for it to be further developed in cooperation +with others in the computer industry. We have agreed to reach out to +leaders in the computer industry such as yourself to obtain your input and +seek your participation in this policy process. + + +2. Communications Industry + +Since unveiling the proposal, Mitchell Kapor and Jerry Berman, EFF's +Washington Office Director, have met with top officials of many of the +communications and electronic publishing firms involved in the current +debate, including the American Newspaper Publishers Association, the +National Cable Television Association, Dun and Bradstreet, AT&T, and the +Electronic Publishers Association.

Although some call them +"multiplexing" equipment, in essence they are all dedicated purpose +computers. As such, they all have software (or firmware or whatever is +appropriate to the vendors architecture and jargon) which dictate their +operation. In many cases, this software is arranged as various packages or +"features" that are licensed (via a right-to-use fee) from the vendor. +These +software features include software for the various module operations as +well +as for the CPU "generic" software. ISDN functionality is usually included +as +one or more of these features (e.g. basic ISDN, D-channel packet, D-channel +backup could all be different feature packages). + +There may be multiple physical variants of each module for use in providing +different serving arrangements in different switches. These may also many +times be distinguished by different pricing levels. At least one vendor has +available a standard, analog line card/line drawer/line frame module and a +different ISDN, 2B1Q compatible line card/line drawer/line frame module. +The +2B1Q ISDN line frame module is to be upgraded in 1992 to be physically and +software compatible with all standard analog line cards as well as the ISDN +2B1Q line cards. + + +Network +----------- + +Making ISDN a viable service will require providing the right physical +equipment and software in the network. Individual physical pieces that +will need to be considered are: + + a. line terminating equipment + b. interoffice trunking equipment (for 64kb clear channel signaling) + c. interoffice facilities (for 64kb clear channel signaling) + d. subscriber loop carrier equipment + + +It is probable that most existing line terminating equipment is not ISDN +capable. The primary reason in most cases will probably have to do with the +need for splitting off the D-channel signaling and routing it through the +switch to the necessary processing modules. Most existing line module +equipment just doesn't provide for this. This does, of course, depend on +the switch vendors equipment design. + +Most trunk interface module equipment now in use is not 64kb clear channel +signaling capable. For at least two major switch vendors, making the +equipment capable will not require provisioning new equipment modules but +will require adding "common equipment" to the existing modules. The common +equipment consists of additional plug-in boards providing the necessary +functionality. The major problem with this upgrade is the complexity of +adding these plug-ins. If you have a trunk interface module that handles +twenty DS-1 lines and they are all in service only two approaches are +available. You can obtain "turn-down releases" on all of the circuits, +busy them out, perform appropriate maintenance activity on the interface +module, add the new circuit packs, download any needed software to the +trunk interface peripheral, and then reverse the previous steps to put the +circuits back in service. The alternative is to provide a "conversion" +trunk interface module (properly equipped of course), transition all DS-1 +lines from the next module to be converted to the conversion module, +convert +the just vacated one, and then continue the process with the next module in +line and the one that was just converted. Both methods are VERY manpower +intensive and therefore expensive to perform. It is also not a quick +process +in terms of overall interval. Manpower must be allocated to this task when +other, higher priority service-impacting activities are not pending. + +Providing full ISDN capability in the interoffice facility network is much +like providing it in the central office trunk interface modules. +Multiplexing +equipment, fiber terminating bays, line repeaters, etc. must be changed out +or upgraded. The major complicating factor here is the number of circuits +that can be involved and the resulting service impacts. + +Subscriber Loop Carrier +-------------------------- + +Subscriber Loop Carrier (SLC) was developed to take advantage of DS1 +signaling to save outside plant investment. By using two pairs to provide +a DS1 span with a capability of 24 circuits, a savings of 22 pairs could be +realized. Most Subscriber Loop Carrier (SLC) equipment being provided today +operates much in the same fashion as standard T-1 equipment. This means +each +individual module provides some kind of grouping of 24 56kb lines. +Different +vendors provide different line capacities such as AT&T's SLC-96 (tm?) +equipment. In order to provide full ISDN capability the equipment must +first +be upgraded to provide 64kb channel service instead of 56kb. Then the +appropiate plug-in cards must be installed to interface with the actual +pair +going toward the subscribers location. The major concern in this serving +arrangement will be the impact on equipment quantities. To serve 2B+D at a +160kb rate will probably require three channels (64kb * 3 = 192kb) on the +SLC module. A large penetration of ISDN could result in having to increase +equipment investment to a level of about three times what it is now. Some +investigation also is needed to determine if ISDN and standard analog lines +can co-exist on the same SLC module. If not, even a small penetration of +ISDN could result in a large requirement for additional equipment. + +Generic SLC architecture looks as follows: + + 24 + 24 +subscribers + | | Lines | | |SLC | DS1 | | __ + |Line | |Dist | |Central | |SLC | o/ \o + |Interface|_______|Frame|_______|Office |_____//_______|Remote |____/\ + |Module | | | |Terminal| // |Terminal| / \ + |_________| |_____| |________| |________| ---- + 2 lines + (1-transmit) + (1-receive ) + + + + + +The arrangement shown here is what is generically termed "dedicated" mode. +Each subscriber has a channel to the switch available at all times. Most +vendors offer enough intelligence in their terminals (usually via +additional +plug-ins) to also provide concentration ratio's ranging from 48 subscribers +vying for 24 channels (2:1) to as high as 5:1. This would mean that of the +120 customers connected to the remote terminal, only 24 could have calls in +progress at once. + +One primary reason for for SLC equipment not being exactly like standard T1 +systems is the need to provide for additional signaling modes required in +the +loop plant. Interoffice trunk signaling generally uses what is termed +2-State +signaling. The far end can signal you as either off-hook or on-hook +(busy/idle, seizure/idle, etc.) Similarly, you can signal the far end an +off-hook or on-hook. Physically, this signaling can take many forms: loop +closed/loop open, battery reversal/normal battery, E lead ground/E lead +open, +etc. Basic station service typically uses 3-State signaling from the +Central +Office (CO) toward the station and 2-State from the station to the CO. The +CO +needs to signal battery applied to the line, battery not applied to the +line, +and alerting (usually ringing voltage). Special stations such as ground +start +lines or coin lines can use 3-State signaling or even higher (the CO needs +to signal a coin station for coin collect, coin return, dialing pad enable, +dialing pad disable, and ringing among others). This requires the SLC +equipment to encode the signaling information in the PCM bitstream +differently than standard T1. + +As an enhancement to this service, some switch vendors make what is termed +"integrated" SLC modules for their switches. All this really does is take +the +central office terminal and integrate it directly into the switch +architecture. The DS1 lines from the remote terminal can then be terminated +directly on the central office switch. This architecture has never "caught +on" in this area because of the difficulty in maintaining load balance +objectives (i.e. you can't move a high usage line to a low usage line +interface module to keep switch usage in balance without moving at least +23 other customers). + + + + +Interoffice Facilities +---------------------- + +In general, interoffice facilities are arranged as follows: + + + + | |________| | | | + |CO | DS1 |DS1 | |Light Fiber | + |Trunk |________|to | |Terminating Bay | + |Interface|________|DSx |________| or |______\ WORLD + |Module |________|Multiplexer| |Digital Radio Bay| / + |_________| |___________| |_________________| + + LFTB - Light Fiber Terminating Bay + DRB - Digital Radio Bay + MUX - DS1-to-DSx Multiplex/Demultiplex Bay + DSX - Digital Signal X-conn (cross-connect) Bay + COTIM - Central Office Trunk Interface Module + DCS - Digital Crossconnect System + +A more detailed breakdown of a CO would look as follows: + + (fiber) + | |_____| | | | + | /| | | _| |________|LFTB|____\ WORLD + | |____|/ |_____|DACS| _| | _| | |____| / + |COTIM| | /| |____| _| | _|DS3| + | | | \|________________|MUX|____|DSX|________| | + | |____|DSX|________________| | _| | |LFTB|_____\ WORLD + |_____| |___| |___| _|___| |____| / + + +Instead of the fiber shown in this drawing, digital radio or cable based +T1, +T1C, and T2 may be used in the interoffice plant. + +Each piece of equipment in this arrangement must be capable of 64kb clear +channel signaling or it cannot be made available on an end-to-end basis. +For +service protection, the trunk paths between two end points are usually +spread over as wide a range of equipment as possible.

But I'll fill it in anyway... + +Everyone knows that ISDN carries synchronous 2B+D, and that each B is +64Kbps packet or circuit switched, and the D is 16Kbps packet +switched. Synchronous means that the data is constantly flowing at +the specified rate. Most modems in use today use asynchronous +transmission, which means that each chunk of information has a +starting indication and an ending indication. + +Packet switched means that the stream of bits is formatted +into packets, and each packet is transported as a unit. Circuit +switched means that the stream of bits goes from one end to another +without being interpreted by the switching equipment. + +There are two different flavors of 2B+D: U and T. ANSI has defined +two different interfaces in the customer's premises, T (or S/T) and U. +The U interface connects directly to the switch over a 0 to 18,000 foot +loop, and uses one pair. The T interface connects to the U interface +through a signal converter called an NT1. It uses two pair (transmit and +receive) and runs at most 1,000 feet. + +The U interface is electrically more sophisticated. The transmission +rate is 80Kbaud and each pair of bits is encoded into four different +voltage levels. This makes the data rate 160Kbps, plus it transmits +and receives in both directions at the same time. It does this by +knowing what it's sending, and subtracting that from what it's +receiving. Then it digitally filters the result. This is necessary +because the local loop to your premises may contain multiple changes +in impedance. That happens when your wire gauge changes, or you have +a tee connection. These impedance changes muddy the digital signal. + +There can be only one device on the U interface, most probably an NT1. +The T interface, on the other hand, can be shared between multiple +devices. This is done because you can hang a telephone, a modem, and +a FAX machine off the same phone line. When a FAX machine calls you, +your FAX machine answers. When a modem calls you, your modem answers, +etc. + +There are three concerns with ISDN: + + o Powering + o Wiring + o Extensions + +Powering + +The current telephone network (POTS -- Plain Old Telephone Service +[seriously]) is powered by the central office. Ever notice that your +phone has a "REN"? That stands for Ringer Equivalence Number. It's +given in units of the standard telephone bell. Your central office +can ring about five of these bells. If the total of all your RENs is +over five, then your phone may not ring. + +ISDN, on the other hand, uses no power from the central office. That seems +like an advantage, but what happens when you lose local power. The central +office still runs because it has its own batteries. But you can't make +calls unless you have your ISDN sets on a UPS. + +Wiring + +POTS phones can and have been wired willy-nilly, in a star configuration, +or bus. Because only two wires are necessary, sometimes only two wires +work. + +ISDN, on the other hand, requires a single stretch of wire with terminators +on both ends, and it requires four wires. + +Extensions + +POTS sets can join into an existing phone call simply by going off hook. +Only one ISDN set can communicate on a B channel at a time. That means +that only the originating or receiving set can communicate. All the +other sets cannot transmit or receive. + +--russ I'm proud to be a humble Quaker. +Peace is not the absence of war.

Times News Service + + Just one week after President Bush signed legislation calling for the +creation of a nationwide computer data "superhighway," a debate has erupted +over whether the government gave an unfair advantage to a joint venture of +IBM and MCI that built and manages a key part of the network. + The IBM-MCI venture, known as Advanced Network and Services, manages a +network called NSFnet, which connects hundreds of research centers and +universities. NSFnet also manages links to dozens of other countries. All +these networks are collectively known as Internet. + Some private competitors say Advanced Network and Services uses its +favored position to squeeze them out of the data-transmission market by +establishing rules that make it difficult to connect to NSFnet. + NSFnet was founded by the National Science Foundation, a federal agency, +and is composed of leased telephone lines that link special computers +called routers, which transmit packages of data to three million users in +33 countries. Data traffic over the NSFnet backbone has doubled in the last +year. + The government wants to develop a national data highway for electronic +commerce, digital video transmissions to homes and vast electronic +libraries that could be drawn on by the nation's schools. + Advanced Network and Services, based in Elmsford, N.Y., was set up last +year as a non-profit corporation with $10 million from International +Business Machines Corp. and MCI Communications Corp. Earlier this year it +set up a for-profit subsidiary, called ANS CO+RE, to sell computer network +services. That led some competitors to complain that Advanced Network and +Services would be able to compete unfairly because of its arrangement with +the government. + People involved in planning for a national data network say it is +essential to provide for fair competition, which will lead rival companies +to offer creative and entrepreneurial services in the hope of building +market share. Without competiton, they say, the government will have +created a monopoly that has little incentive to innovate. + "This is the first major communication business to be born under the +deregulation era," said David Farber, a computer scientist at the +University of Pennsylvania and a pioneer in data networking. "This hasn't +happened since the growth of the telephone industry. You want it to be a +business that doesn't repeat the errors of the past." + In recent years, the National Science Foundation has tried to shift its +operations and ownership of NSFnet to Advanced Network and Services. And it +will try to establish competition through contracts for networks to compete +with NSFnet next year. + But there is no level playing field, complained William L. Schrader, +president of Performance Systems International Inc., a Reston, Va., company +that provides commercial data connections to Internet. + He made public two letters between officials of Advanced Network and +Services and the National Science Foundation that he said gave the company +unfair control over access to the network. The result, he added, was that +the government turned over valuable public property to a private company. + "It's like taking a federal park and giving it to Kmart," Schrader said. +"It's not right, and it isn't going to stand. As a taxpayer, I think it's +disgusting." + Performance Systems and several other companies have set up an +alternative to NSFnet, known as a CIX. + Schrader said his company and the venture of IBM and MCI were competing +for the same customers but unlike his rival he lacked a federal subsidy. He +said he might ask the Internal Revenue Service to look at the business +relationship between Advanced Network's non-profit and for-profit +operations. + Allan Weis, the president of Advanced Network, disputed that his company +had an unfair advantage. "It's a very competitive environment right now," +he said. "We have lost quite a few bids to PSI and to other competitors as +well." + At the National Science Foundation, Stephen Wolff, director of its +networking division, said IBM and MCI had overbuilt the network and were +selling commercial service based on the excess capacity that was available. + A number of organizations are working informally to settle the dispute. + "I think it's a mess," said Mitchell D. Kapor, the founder of Lotus +Development Corp. and now head of the Electronic Frontier Foundation, a +public-interest group focusing on public policy issues surrounding data +networks. "Nobody should have an unfair advantage. This is important +because we're talking about something that is in its infancy but that one +day could be on the order of the personal computer industry." +------- + + + + diff --git a/textfiles.com/computers/1pt4mb.inf b/textfiles.com/computers/1pt4mb.inf new file mode 100644 index 00000000..dc81d624 --- /dev/null +++ b/textfiles.com/computers/1pt4mb.inf @@ -0,0 +1,98 @@ +------------------------------------------------------------------------------ +This file was downloaded from ALIENS BBS ISRAEL, the BEST BBS in ISRAEL! +Call now! 052-506539 24H 250Mb on-line! +------------------------------------------------------------------------------ + + +NOTES ON THE USE OF 1.4 MB DRIVES IN AT-COMPATIBLES: + +I wasn't long after 1.4 Mb drives became available on the +aftermarket that users discovered there are significant problems +is applying then to AT's. Many of Second Nature's users have +asked for help or advice, as SecNat has a feature to help in 3.5" +disk installation on older AT's with no BIOS 3.5" support. All +sorts of strange stories are filtering back from the people who +sell such drives, some of it contradictory, so I felt it was time +to get all the facts in one place. + +The use of 720k 3.5" drives is non-controversial, and the drive +manufacturers' instructions are generally adequate. 1.4 Mb +drives, however, _will_not_ and _cannot_ work "out of the box", +due to a _basic_hardware_incompatibility_: + +a) The Western Digital AT-type controllers (1002 & 1003 WA2) +_hard-wire_ the state of the /Reduced Write Current output on Pin +2 to the _data_rate_in_use_: Low for 300 kHz, High for +_all_others_. 1.4 Mb drives use the 500 kHz data rate for 1.4 Mb +disks, and the 250 kHz data rate for 720k media. THUS /RWC IS +ALWAYS HIGH! + +b) The 1.4 Mb drive requires that /RWC be LOW for 720k media, and +HIGH for 1.4 Mb media. Think of it being much like tape bias on +a cassette deck -- if it's not matched properly to the media, +full fidelity recording is _impossible_. + +Note that both of the above factors are _built_into_ the +hardware, and CANNOT be changed by the BIOS, or software drivers! +Thus 1.4 Mb drives, when simply plunked in an hooked up, CANNOT +properly record on 720k media, and will normally TRASH as disk, +if a write is attempted! Two solutions are known to work: + +1) A switch on the drive allowing /RWC for the 1.4 Mb drive to +be independent of input Pin 2's state. This may be done by +installing a small toggle switch in the extra front panel space +of the 3.5" to 5" adapter used for AT-mounted 1.4 Mb drives. The +connection to pin 2 of the cable should be broken (on the drive +side of the connector), and the switch wired so that in the +"720k" position the circuitry previously connected to Pin 2 is +closed to Logic Ground. The switch is then open in the other +"1.4 Mb" position, and produces Low and High levels to /RWC, +respectively. If 1.4 Mb BIOS support is available (if it's an +option in your SETUP program), operation will be exactly like a +PS/2 1.4 Mb drive, EXCEPT you must set the switch appropriately +to the MEDIA IN USE. If you do not have BIOS support, you may +use DRIVER.SYS to define the drive, with an entry like: + + PCDOS 3.3: DEVICE=DRIVER.SYS /D:1 /F:7 /S:18 /C + + AST MS-DOS 3.2: DEVICE=DRIVER.SYS /D:1 /F:4 /S:18 /C + ^ + (See your DOS Manual for the + correct /F: number for 1.4 Mb) + +Command syntax for formatting will be as described in your DOS +Manual. REMEMBER TO USE THE DRIVE LETTER ASSIGNED BY DRIVER.SYS +WHEN FORMATTING, if you do not have BIOS support! + +2) The drive can be internally modified to control the state of +/RWC from the sensor for the extra hole in the body of a 1.4 Mb +diskette. Surprisingly I know of no commercial drive that does +this, but I verified it's practicality by today actually +modifying an Astro brand Internal Drive Kit, supplied as type 1), +above. Regrettably, modifying the Mitsubishi drive in the Astro +required milling of the casting, and modification of numerous +internal parts, but with some 4 hours work it was done, and does +indeed perform automatically as desired. I suspect that the +absence of Media Type Sensors in most 1.4 Mb drives is due to the +proximity of the required sensor location to the Eject Button +mechanism, usually carried over from the manufacturers' earlier +720k drive. With this type of media-sensing drive operation is +exactly as in a PS/2, in that the only operator decision to be +made is matching the Formatting commands to the actual type of +media in use. There is an added advantage in that you can't +"wipe out" the media, by writing to, or formatting, a 720k +diskette with /RWC High -- a mistake that usually requires a +powerful bulk eraser to repair, and causes the loss of any data +already on the disk. Anyone wishing to supply a drive of this +type may contact me for full particulars of the Media Sensor to +/RWC interconnection. + +I'll note in closing that the Astro unit (advertised in +InfoWorld) is supplied with software said to work with any DOS +2.0 and above, at $295, however if you have BIOS support you may +use PCDOS 3.3 (or AST MS-DOS 3.2), instead of the supplied +software.

They are +probably manufacturer's part numbers for a particular Hayes clone modem, but, +they could just as easily be spare tires for a volvo motorcycle! + +(2) The SC11005 chip called out in the instructions is also not an INTEL +number; it is a SIERRA number. Specifically, it is a SIERRA V.22 bis modem +filter (don't recall all the exact specs). + +(3) They instruct you to remove the SIERRA SC11005 chip and replace it with +an SC11020. In the first place, the SC11020 is essentially a custom +microprocessor (not a filter of any sort), in the second place, the SC11020 +has about twice as many pins as the SC11005! Not to mention it uses +different power supply connections and voltages and may possible blow up if +you could get it rigged in just right. An experienced technician would +notice that right off, but again, some have just enough experience to feel +they can do this, but do not realize what is going on until they have already +hacked the SC11005 (or some other part) out of the modem (if they even FOUND +one in the first place!). + +(4) To the best of my knowledge, there is no way to upgrade a V.22bis modem +to any kind of 9600 bps modem no matter what you do.

You may recognize this as the +"noise filter" circuit explained in a number of BBS files over the past +couple of years. + Since Lap-M error correction is a SOFTWARE function, it goes without +saying that you cannot add Lap-M error correction to a modem simply by adding +a series RC network between tip and ring on the phone jack! + To add Lap-M error correction requires the addition of software requiring +thousands of man hours to write and debug, and a microprocessor capable of +executing the software in real time. At 9600 bps this is no small +requirement! + +(7) A 9600 bps modem requires support circuitry at least 10 times better +(higher quality, lower distortion, better echo-canceling, etc.) than 2400 bps +modems.

The method described replaces 16 + 256K dynamic RAM chips with 16 one megabit dynamic RAM chips installed + in chip sockets. Reinstallation of the ST's metal shield cover is also + not impaired. + + The beauty of this modification is that pin compatibility is simplified + by the use of sockets instead of directly soldering the 1 meg RAM chips + (DRAMs) to the motherboard and by the fact that the removed bank of + sixteen perfectly reusable 256K DRAMs can be resold by you to persons + upgrading 520STfm computers to 1 megabyte. + + If you use this upgrade method, I recommend that you also use the same + high quality low contact resistance sockets that I used and have listed + below, than to use any other standard sockets. These are the type and + quality which are used on expansion boards made for the IBM clones. + + I originally wrote this procedure to aid me in upgrading my own + 1040ST's memory to 2.5 megabytes because I didn't trust myself not + making mistakes and possibly damaging any of the electronic components, + especially the new DRAMs which I didn't consider cheap. I might note + that my 1040ST's pc-board was marked Rev 4, but I don't believe that + any other recent board revisions (if they exist) for boards with 32 + 256K DRAMs installed should affect this procedure. + + + Disclaimer of Liability + + + I make no claim that this modification will work for you.

This + provides padding for the components and a conductor for static + electricity. + + + Precautions + + + Since the slightest static discharge could easily damage + components on your computers pc-board, always keep one hand on the + metal foil bonded along the outer rim of the pc-board before and during + touching any part of the pc-board or its components. Avoid working on + this project when the humidity is low. + + 3 + + + Procedure + + + 1. After removing the pc-board from the insides of your computer, + desolder and remove the front 16 256K chips (U33 through U45 and U16 + through U30). + + 2. Using the Exacto knife, cut the following traces on the top side of + the pc-board: + + a. Between U30's pin 1 and U61's pin 1. + b. Between pin 14's of U33 through U45 and U16 through U30 and + other pin 14's of U46 through U61. + c. Between the thru-hole (nearest to pin 1 in center of U32) of + U32 and U46's pin 1. (Note: This thru-hole traces to U32's pin 1 + on the underside of the board.) + + 3. Using the Exacto knife, cut the following traces on the bottom side + of the pc-board: + + a. Between U30's pin 1 and the 32 ohm resistor R76. + b. Between U32's pins 2 and 14. Do the same for U33 through U45 + and U16 through U30. + c. Between U30's pin 4 and U15's pin 8. (Note: Cut the trace after + it goes through the board to the bottom side near resistor R91, + but before it reappears on the top of the board via another + thru-hole. + d. Between U32's pin 14 and the thru-hole located between U32 and + U33. + + 4. Preparing New Sockets and Soldering Them Inplace + + a. On all 16 new sockets, remove the internals of pin 4. + b. On all 16 new sockets, bend all pins 1 and 17 flat against + their bottom then up against their outer side. + c. On 14 of the new sockets, bend pin 18's flat against their + bottom and pointing straight out to the side. + d. On the remaining two, bend both pin 18's flat against their + bottom but back and down so it will just reach and fit into the + pc-board hole of it's adjacent pin (pin 17). These two sockets + will be installed and soldered with the socket's pin 18 going into + the old 256K chip's pin 16 hole below the new socket's pin 17. + Trial fit these two sockets at this time. + e. Using a pair of scissors, cut pieces of "Socket Wrap-ID" + plastic markers for sandwiching them between the new sockets and + the pc-board during installation. These little plastic markers + should be cut so as to electrically isolate the socket's pins 1 + and 17 from leads and traces on the pc-board, and from pin 18 of + the socket for the two separately prepared sockets above, but also + so as not to interfere with seating the socket's four pads flush + with the top of the pc-board upon installation. + f. Solder the two sockets with the bent back pin 18 and markers + + 4 + + + into U30 and U33. + g. Solder the remaining sockets with markers into U34 through U45 + and U16 through U29. Pin 18 of these socket's must be soldered to + the top of the board at the nearest thru-hole that the pin 18 just + barely reaches. Use plenty of heat as these thru-holes are big + heat sinks. + + 5. Mounting The New 33 Ohm Resistor + + a. Install a new 33 ohm resistor on the pc-board by drilling two + small holes from the top at points near capacitor C55 and resistor + R70. Make sure you don't drill through a trace on the other side + by holding the pc-board up to a bright light and marking the spots + with a pencil. + + 6. Wiring + + Wire the following connections on the top side of the board: + + a. Between U32's new socket's pins 1 and 17 and a thru-hole on the + pc-board between U32 and U33. This thru hole is the only one that + has a trace that run to another thru-hole between U46 and U47 on + the top side of the board. + b. Between U16's new socket's pins 1 and 17, and pin 2 of U54. + Solder the wire directly to the side of the chips pin 2. + c. Between each of the remaining new socket's pin 1 and 17 and a + thru-hole in back of each 256K RAM chip (i.e., U47 through U53 and + U55 through U61). These thru-holes are the ones that you will find + traces back to either pin 2 or pin 14 of U47 through U61 and then + trace over toward U22, U23, U26, and U27. Actually, pins 2 and 14 + are tied together on the bottom of the board for every 256K RAM + chip still installed. So that's 14 more wires altogether (i.e., + each new RAM chip's pins 1 and 17 will be connected to the pins 2 + and 14 of the 256K chip directly in back of it. + + Wire the following connections on the bottom side of the board + (Note: all pin numbers here refer to the pin numbers on the + pc-board, not the pin numbers of the new sockets or new ram + chips): + + d. Between U15's pin 64 and one side of the new 33 ohm resistor. + e. Between all pin 14's of U32 through U45 and U16 through U30, + and the other side of the new 33 ohm resistor. + f. Between all pin 2's of U32 through U45 and U16 through U30, and + the thru-hole near R91 which had its trace cut to U30's pin 4. + This thru-hole traces back on top of the pc-board under the bank + of resistors and over to U15. + g. Between U61's pin 1, U30's pin 4, and the cut trace side of + resistor R76. + h. Between U30's pin 1 and U61's pin 3. + + 8. Inspect all solder joints with the magnifier for solder shorts and + + 5 + + + faulty connections. Verify that all connections were made correct. + + 9. Install the new 1 meg RAM chips into their new sockets. + + 10.That's it! Clean isn't it?

The Courier V.32bis, Courier HST Dual Standard and Shared Access +Modem Sharing Kits are the products currently included in the program. Field +upgrades will be available for $299 as soon as the CCITT 28.8 Kbps draft +recommendation is completed. Official approval of the standard is not +expected until January, 1994. + "The CCITT-proposed 28.8 Kbps standard won't be a reality for most +manufacturers until 1994," said Jonathan Zakin, U.S. Robotics executive vice +president, sales and marketing. "By offering modems ready for 28.8 Kbps now, +we're providing insurance against technical obsolescence. Customers can +purchase a Courier high-speed modem or Shared Access Modem Sharing Kit now +and take advantage of the most updated technology available. When the 28.8 +Kbps standard becomes available later, they'll already have a cost-effective +upgrade option and won't have to re-invest in new equipment." + "Key to the 28.8 Kbps program is the fact that the upgrade to the +Courier high-speed modems and Shared Access Modem Sharing Kits can be +completed by the end user at their worksite, which reduces their `down' time +and eliminates excess costs like shipping and handling," continued Zakin. +"You may hear about other 28.8 Kbps modems that are available now, but until +the standard is defined, no one knows what hardware will be needed to comply. +Our unique modem architecture makes future `field' upgrades a realistic and +simple procedure." + Because of U. S. Robotics' advanced modular modem architecture, the +company's Courier V.32bis, Courier HST Dual Standard, and Shared Access modems +are readily upgradable to 28.8Kbps. The modems are made up of a motherboard and +a smaller daughterboard, which holds the modems' microprocessors and firmware. +The current, high-speed daughterboard can easily be replaced with a new board +containing the 28.8 Kbps CCITT standard. U.S. Robotics is the only modem +manufacturer to implement this kind of flexible design. + "In the CClTT, the previously called `V.FAST' standard has gained +universal support at the 28.8Kbps speed," said Dale Walsh, U.S. Robotics vice +president, advanced development and participant in the CCITT committee on the +28.8 Kbps standard, "This is how our modular architecture works. The data +pump (which executes the modulation and demodulation of the data), and the +key controller functions (which perform the data compression, error control +and the AT command set) are on one board, making upgrades simple. We can +easily make the data pump faster and upgrade the controller functions to keep +up with the new speed. It's all in just one small plug-in card." + Because compatibility with CCITT standards is crucial, U.S. Robotics' +availability and implementation of the 28.8Kbps standard will depend on the +CClTT's progress. At this time, the standard is expected to define a connect +speed of 28.8 Kbps, two times faster than V.32bis, the fastest CCITT +standard now available. + U.S. Robotics is one of the first vendors to announce a program for +28.8Kbps compatibility. The company has a history of industry "firsts," +including the first CCITT V.32bis modem from a major manufacturer, the first +self-managing modem management system and the first portable CCITT V.32 +modem. + U.S. Robotics will upgrade any Modem Sharing Kit to 28.8Kbps. Current +Courier models, which have the smaller footprint and a higher, 57.6 Kbps DCE +to DTE (modem-to-computer) interface speed, are also upgradable. The +company's upgrade program does not include WorldPort and Sportster modems. + U. S. Robotics Courier modems offer a wide range of features, including +fax, remote configuration, and synchronous capabilities. The Shared Access +Modem Sharing Kits, which began shipping in March, 1992, allow for the +pooling of modems on a LAN so that a LAN user can access them for dial-in or +dial-out communications. + The following products will be upgradable to 28.8 Kbps: + + Courier V.32 bis, internal and external (57,600 bps versions only) + Courier HST Dual Standard, internal and external (57,600 bps versions only) + Courier V.32 bis FAX, internal and external + Courier HST Dual Standard FAX, internal and external + Shared Access Modem Sharing Kit Single Port and Dual Port + + THE CCITT 28.8 KBPS STANDARD: SOME BACKGROUND + --------------------------------------------- + + The standard for 28.8 Kbps dial-up communications being developed by the +CCITT will stretch the limits of dial-up telephone lines. But don't expect +to be sending files at top speeds immediately. + Dale Walsh, vice president for advanced development at U.S. Robotics, +Inc., cautions that most users won't be able to achieve the maximum speeds +permitted under the standard right away. When the standard is adopted, modems +that conform should be able to transmit at 19.2 Kbps on lines where a modem +conforming to V.32bis (the current high-speed standard) can now transmit at +14.4 Kbs. But Walsh, a member of the CCITT committee developing the +standard, says it is being formulated with the increasing digitization of +dial-up phone networks in mind. + The improved quality of phone lines, as much as any modem technology +improvements, has made high speed dial-up communications possible" says +Walsh. "We are designing the standard keeping in mind that phone networks +will use more and more digital circuits and digital central office switches." + Consequently, speeds in the neighborhood of 28.8 Kbps will be the +exception, rather than the rule--at least until the public switched +telephone network becomes completely digital. + "I'd say when it's finished in a year or so, the standard will allow +19.2 Kbps transmissions on 80 percent of all lines, 24 Kbps on 50 percent of +all lines, and 28.8 Kbps communications on 20 percent of all lines," says +Walsh, who also helped develop the CCITT V.32bis standard for 14.4 Kbps +dial-up communications. "As the phone networks improve, top speeds will be +more easily achieved, so I think it's more realistic to think of it as a +19.2 Kbps standard that is sometimes capable of higher speeds. + A common misconception is that the coming 28.8 Kbps standard will allow +speeds of 115.2 Kbps, when combined with V.42bis data compression. Walsh noted +that such calculations are based on an assumption that V.42bis allows 4 to 1 +data compression. Outside the lab, V.42bis allows compression ratios between +2 to 1 and 3 to 1, meaning that under REAL LIFE conditions, the forthcoming +standard will allow maximum throughput of about 86.4 Kbps. + "It's a mistake to use the 28.8 number and max everything out from that," +said Walsh. + Not that the 28.8 Kbps standard doesn't have its advantages. After all, +19.2 Kbps is an improvement over 14.4 Kbps. And the forthcoming standard will +adjust for line conditions, a critical factor in high-speed data +communications--like no previous standard. The standard under development +will include a "probing" function that the modem can use to "sound out" the +quality of the phone line. That will allow the modem to optimize transmissions +to take advantage of available bandwidth. + "We are still working on the training sequences," says Walsh. "But before +transmission starts, the standard will enable the modem to determine what band- +width is available and how to best position the signal to match available band- +width." + The standard achieves higher speeds through its ability to use more of a +line's bandwidth, not just the center portion of the channel used under current +standards. + "It will more closely match the modulation scheme to what's available," +says Walsh. "That way, the modem can shape the transmissions to adapt +precisely to the channel, which is very important if you want to transmit at +high speeds. + The most recent committee meeting was held last month. Still to be +agreed upon are such critical issues as training sequences, coding schemes, and +signaling rates. Walsh said he expects the committee to reach final agreement +in 1993, with official CCITT adoption likely in 1994. + While some have taken to calling the standard under development V.Last, +Walsh isn't convinced this will be the final modem standard. After all, he +notes, no one thought dial-up phone lines would ever be this noise-free, and +further advances in that area could make even higher speed dial-up +communication possible. + "I'm certain we'll have at least a fax version of this standard as the +quality of phone lines keep improving," he said.

Perhaps you have a printer with a serial port and a +telephon modem, as I do. The first idea might be to go to your dealer +expecting that he has an extension card for a few bucks. He hasn't, +and you get curious about whether the ATARI can be regarded as a real +computer. Anyway, you need a solution and don't want to trade your +ATARI for one of those clones and are even more upset about the idea +of exchanging the connectors any time you use another peripheral. This +can be the point when you consider looking more seriously into the +hardware detecting that there is this MIDI port you never spent any +thought about. It is just there for those people who cannot play piano +properly and compensate for this by buying a lot of electronic parts +hoping that they can improve their music by it :-). You may even have +a different opinion about them. You know, however, for sure that *you* +won't use this port. Therefore it seems to be a good idea to use it +for your own purposes. + +The above describes precisely my thoughts leading to the modification +of my ATARI described below. It's just an easy, quick and cheap +hardware hack -- it doesn't meet the RS232 standards -- but it works! +I used a RS232 receiver to receive *and* send the signals, because +this was the chip I found somewhere in my old computer (a 6800 !!) +where it served the same purpose. However, note that nowadays +RS232 tranceivers are available which should be used instead. + +Note that the description below applies *only* to the ATARI 520 ST and +things may be different for the 1040. Additionally, the description +can be, of course, incorrect. Therefore you should verify that the +modifications described below are correct by consulting the proper +sources. In any way, modifications according to the description below +carried out by you are on your own risk. In particular, you should be +aware that the warranty for your computer will expire after opening +it. + + +1) A COMMUNICATION PORT + +The first thing you have to decide is what communication port you like to +use. I chose the MIDI IN port for three reasons: + - I won't use MIDI after the modification. + - Connectors for this communication port are easily available and cheap. + - Three of the five pins aren't used. + +The drawback of this solution is that you might easily confuse the +MIDI IN port with the MIDI OUT port when plugging in your connector +which can result in blowing up your peripheral. + +I use the following pin assignment: + Pin 1 = RS232 OUT + Pin 2 = GND + Pin 3 = RS232 IN +Note that pin 4 & 5 are already used. + +Pin layout of the communication port seen from inside: + + 1 3 + + 4 5 + 2 + +NOTE: In a lot of sources including my ATARI manual I found a different pin + layout which, however, seems to be wrong. + +SOLDERING: Pin 2 of MIDI IN has to be connected with pin 2 of MIDI OUT. +NOTE: These pins are only accessible from the bottom side of the board. + + +2) REWIRING THE MIDI ACIA + +The wiring of the MIDI ACIA has to be changed. We have to rewire the +Tx-Data and Rx-Data pins, because we want to use a different +driver. Additionally, the Tx-Clk and Rx-Clk must be connected to a +different clock, because a fixed baud rate of 7812.5 is probably not +appropriate. In the ATARI 520 ST the 6850 sitting next to the sound +chip -- the YM 2149 -- is the right chip. + +CUTTING: Pin 2 (Rx Data), pin 3 (Rx Clk), pin 4 (Tx Clk) and pin 6 (Tx Data). + + +3) A NEW BAUD RATE GENERATOR + +Timer A of the MFP 68091 is not used and can be employed as a baud +rate generator for our ACIA. A tiny assembler program setting the +correct baud rate is given below. I usually run this program at boot +time from my AUTO folder. A more sophisticated solution could be to +write an accessory to set the baud rate. + +SOLDERING: Connect pin 3 (Rx Clk) and pin 4 (Tx Clk) of the MIDI ACIA with + pin 13 (Timer A Out) of the MFP. + + +4) A RS232 DRIVER + +As I said above, I used a RS232 receiver (SN 75189) for both +transmitting and receiving. That means that the outgoing signal does +*not* conform to the RS232 voltage level specification. However, this +cheap kludge always worked. + +SOLDERING: - Mount a 75189 (RS232 receiver) on a small circuit board. + - Connect pin 14 (Vcc) of the 75189 with Vcc, e.g., with pin 14 + of a 7404. + - Connect pin 7 (Gnd) of the 75189 with Gnd, e.g., with pin 7 + of a 7404. + - Connect pin 13 (4A) of the 75189 with pin 3 (RS232 In) + of the MIDI IN port . + - Connect pin 11 (4Y) of the 75189 with pin 2 (Rx Data) of + the MIDI ACIA . + - Connect a resistor (1K Ohm, probably 10K works as well) with + pin 11 (4Y) of the 75189 and Vcc. + - Connect pin 3 (1Y) of the 75189 with pin 1 (RS232 Out) of + the MIDI IN port. + - Connect a resistor (1K Ohm) with pin 3 (1Y) of the 75189 + and Vcc. + - Connect pin 1 (1A) of the 75189 with pin 6 (Tx Data) of + the MIDI ACIA. + - Finally, you should install the circuit board somewhere on + the motherboard. + +These are all hardware modifications in order to get a second RS232 +port. There is, however, some software necessary before you actually +can use the new port. First, the baud rate has to be programmed into +timer A. A small assembly program is given below. Second, the ACIA +registers have to be set up to the proper values. At boot time they +get set to 8-Bit, no-parity. Third, you have to write programs which +actually use the port. I, for my part, changed GEM-KERMIT and my +TERMINAL accessory in order to work with the MIDI port. + +SETTING THE BAUD RATE: + +* Initialize Timer A as baud rate generator for MIDI ACIA +* +* Bernhard Nebel 14.12.86 +* +* valid values for data and control are: +* baud control data +* 19200 1 1 +* 9600 1 2 +* 4800 1 4 +* 3600 1 5 +* 2400 1 8 +* 2000 1 10 +* 1800 1 11 +* 1200 1 16 +* 600 1 32 +* 300 1 64 +* 200 1 96 +* 150 1 128 +* 134 1 143 +* 110 1 175 +* 75 2 64 +* 50 2 96 + + +gemdos equ 1 +bios equ 13 +xbios equ 14 + +Pterm0 equ $00 +Cconws equ $09 + +rsconf equ 15 +setprt equ 33 +xbtimer equ 31 + + +modem .equ * + + move.l #-1,-(sp) vector + move.w #64,-(sp) data + move.w #1,-(sp) control + move.w #0,-(sp) timer = A + move.w #xbtimer,-(sp) + trap #xbios + add.l #12,sp + + move.l #mess,-(sp) + move.w #Cconws,-(sp) + trap #gemdos + addq.l #6,sp + + move.w #Pterm0,-(sp) + trap #gemdos + +* strings + + .even +mess dc.b "MIDI port initialized (300 baud, 8-Bit, Nosync).",$0D,$0A,0 + +Have fun - Bernhard +} MAILER STANFORD 7/15/87 +v Mail Delivery Subsy NEBEL@DB0TUI11.BITN 7/15/87 Returned mail: User unknown +Acknowledge-To: + + +$ \ No newline at end of file diff --git a/textfiles.com/computers/2w93358a.txt b/textfiles.com/computers/2w93358a.txt new file mode 100644 index 00000000..913e5801 --- /dev/null +++ b/textfiles.com/computers/2w93358a.txt @@ -0,0 +1,83 @@ + Guide to PGP Operations in a Secure Environment + +The following document provides a series of notes and examples which are designed +to help the PGP novice user to properly maintain and care for public keys in a +secure environment using the PGP utility software. + +Item Activity Operative Command Results/Disposition + No. + 1 Install System Set DOS PATH command in + AUTOEXEC.BAT so that DOS can + always find PGP; Set the DOS + + + ENV variable TZ=-3 (EST).

I know that I was. I say WAS because I +now get 486 class performance out of my old 386 system and I did not +spend a fortune. If you have a 386 system you may also be interested in +this upgrade. + +THE Cx486DLC + +Introduced in the summer of 1992, Cyrix produces a processor called the +Cx486DLC. The Cx486DLC is a cross between Intel's 386DX and 486SX. The +Cx486DLC is pin compatible with the 386DX and instruction set compatible +with the 486SX. Like the 486SX the Cx486DLC contains an internal cache +and an optimized execution unit. The cache and optimized execution unit +are the main reasons that a 486 is faster then a 386 at the same clock +rate. By replacing your 386 CPU with the Cx486DLC you get 486 class +performance without replacing your PC. + +To be sure that your PC is upgradable to the Cx486DLC, check through the +following: + +1 - The PC must be based on a 386DX (sometimes called a 386 or 80386) +from Intel or AMD. PCs based on the 386SX can not use this upgrade. + +2 - Remove the cover of your PC and locate the CPU. It is a 1.5 inch +square IC. It should be labeled Intel or AMD 386DX. There must be +about 2 inches of open space above the CPU. The Cx486DLC runs hotter +than the 386DX and typically requires a heat sink mounted on top of the +chip. The additional space is required by the heat sink. + +3 - You should have a socket on the motherboard for a 387 math +co-processor. You may have a 387 already installed. + +If your PC meets all of the above requirements you can perform the +upgrade. I checked around for the best prices on the Cyrix chips and +found that CompuAdd express offers the best deal. They sell upgrade +kits for their line of scalable PCs. Each upgrade kit includes the +Cx486DLC, a Cyrix math co-processor, the heat sink and a chip puller for +removing the old 386 CPU. While they are intended for use with +CompuAdd's line of PCs, they are ideal for our upgrade and are quite a +bargain. At the time I'm writing this, the price of a 33 Mhz upgrade +kit has just dropped to $159 and a 40 Mhz kit has dropped to $249. A +math co-processor alone costs about $100. The upgrade kit to order if +your PC runs at 33 Mhz or slower is the 433DLC. The 40 Mhz kit is the +440DLC. + +PERFORMING THE UPGRADE + +Remove the cover from your PC, locate the 386 CPU. Note the location of +pin 1 on the CPU. Pin 1 is marked by a dot or cut off corner on the +chip. Use the chip puller to carefully pry the CPU out of it's socket. +Work slowly around the chip as to not bend any of the pins. Place the +486DLC into the socket with pin 1 in the same orientation as before. +Carefully press the chip into the socket. Once the chip is in place, +power on the PC, it should beep and power up normally. Power down the +PC, install the heat sink on top of the Cx486DLC and install the math +co-processor as instructed in the manual for the PC (you may need to +move a jumper in addition to installing the chip). Replace the cover +and you are ready to go. The PC should now run normally. To get the +full speed increase you will also need a program that activates the +Cx486DLC's cache. I've written such a program, called CYINIT. You +download a copy of CYINIT (in the archive 386486.ZIP) from both +Compuserve or Genie. It is in the IBMAPP section on Compuserve and in +Don Lancaster's PSRT on Genie. If would like a copy on disk, I will +provide one if you send me a check for $10.00. Once the system is up +and running add CYINIT to your autoexec.bat file. That way the cache +will automatically be activated when you start your PC. + +THE PERFORMANCE IMPROVEMENT + +I've upgraded several systems and found that the CPU performance +typically improves about 50%. Figure 1 shows the typical improvement +shown in the ZD Labs benchmark tests. The system upgraded was a 33 Mhz +386DX with a 64 K external cache and an Intel 387 math coprocessor (also +called an FPU - Floating Point Unit). The performance improvement varied +with the different tests, but averaged out to about a 50 % improvement. +The FPU test also showed that the Cyrix math coprocessor offered a large +speed gain over the Intel math coprocessor. Figure 2 compares the +performance of a 33 Mhz 386, a 33 Mhz Cx486DLC, a 33 Mhz 486DX, a 40 Mhz +Cx486DLC and a 66 Mhz 486DX2 running the 386 instruction mix from the ZD +Labs benchmark. As it shows the 486DLC gives 486 class performance to +your old 386 PC at a bargain price. + +RESOURCE LIST + +Cyrix +2703 North Central Expressway +Richardson, Texas 75080 + +In my article on upgrading your 386 PC to a 486.

This type of work commonly +involves the manipulation of files between 1 and 200 megabytes in +size. In the course of writing and copying such data, we believe +we've run across 2 bugs.

The included files +2048.COM and 2000.COM are the compiled versions of 32MEG.ASM with +BUFSIZE set to 2048 and 2000 respectively. + +The assembly source was compiled and linked with Borland's +assembler TASM v1.01 and linker TLINK v2.0 as follows: + + tasm 32meg + tlink /t 32meg + +I tested the programs in the root directory of my C: which is a +Connor CP-3104 106meg harddrive.

However, when +BUFSIZE is changed to 2000, 2 things happen. First, it takes +nearly twice as long to write the file. Given the fact that Dos +clusters and BIOS disk sectors are always powers of 2, it is not +unreasonable to expect that some additional magic must happen +behind the scenes when such abitrary and rather inconsiderate +byte counts are written. BUT, this was not expected; The +resulting file should have been 43,008,000 bytes long. It was +33,554,000 bytes long; the highest even multiple of 2000 below 32 +megabytes. + +A run of 'CHKDSK /F' produced 'Allocation error in C:\32MEG.DAT, +size adjusted'.

There are advantages +(and disadvantages) to having a large register file. The register file of +the 80486 is definitely too small to avail itself to the advantages. This +is particularly exacerbated by the fact that the CPU registers of the 80486 +are not really quite as general purpose as one might wish. In fact, all of +them are dedicated to certain special tasks, such as: + +EAX, EDX Dedicated to multiplication/division operations +EDX Dedicated to some I/O operations +EBX, EBP Dedicated to serve as base registers for some addressing modes +ECX Dedicated to serve as a counter in LOOP instructions +ESP Dedicated to serve as a stack pointer +ESI, EDI Dedicated to serve as pointers in string instructions and as + index registers in some addressing modes + +On the other hand, on the MC68040 the eight 32-bit data registers D0 to D7 +are genuinely general purpose without any restrictions or specific tasks +imposed on them. Of the eight 32-bit address registers A0 to A7, only A7 +is dedicated as a stack pointer. The user is free to use the other seven +resgisters A0 to A6 in any possible way. + + From the point of view of the CPU register file, the MC68040 has a +very clear advantage. It is much better equipped to retain intermediate +results during a program run, thus reducing CPU-memory traffic. From this +standpoint, the MC68040 even has a slight edge over the VAX architecture. +The VAX (any VAX model) also has sixteen 32-bit general-purpose registers. +However, only 12 of those (as opposed to the 68040's 15) can be used freely +by the programmer. Of the four VAX dedicated registers, one is used as a +program counter and another as a stack pointer. The program counter is +completely separate on both the MC68040 and the 80486 and is not included in +the general-purpose registers. + + +FPU General-Purpose Registers + + Both systems have eight 80-bit registers, providing a large range for +floating-point number representation and a high level of precision. The only +differnce between the two is that the 80486 FPU registers are organized as a +stack, while those of the MC68040 are accessed directly, as its integer CPU +registers. Because of the stack organization the 80486 might have a slight +edge from the standpoint of compiler generation (for that part of the compiler +dealing with floating-point operations). + + +MMU on Chip + + The 80486 has a regular MMU on chip for the control and management of +its memory. The MC68040 has two MMUs: one for code and one for data. This +duality, supported by a separate operand data bus, allows the control unit to +handle instruction and operand fetching simultaneously in parallel and enhances +the handling of the instruction pipeline. Of course, the external bus leading +to the off-chip main memory is single (32-bit data, 32-bit address), and it is +shared by instructions and data operands. With a reasonable on-chip cache hit +ratio, the off-chip bus would be used less often. + + +Cache on Chip + + The total on-chip cache of both systems is 8 kbytes. Interestingly +enough, they have the same parameters: both are four-way set-associative with +16 bytes per line. The difference is that while the 80486 on-chip 8k cache +is mixed, storing both code and data the MC68040 cache is subdivided into two +equal parts: a 4-kbyte data cache and a 4-kbyte code cache. Each cache is +controlled by the respective MMU, mentioned above. The advantage, as in the +MMU case, is the provision of two parallel paths for code and data, resulting +in an overall speedup of operation. + + +Segmentation + + The Intel 80x86 family implements segmentation, while the M68000 family +does not. The earlier Intel systems (8086, 80286) were plagued with the upper +64-kbyte segment size limit, starting with the 80386 and so on, the segment sizecan be made as high as 4 Gbytes (maximum size of the physical memory), +effectively removing the segmentation feature by the decision of the user. +Therefore, as far as segmentation is concerned, the 80486 and MC68040 are +comparable. The 80486 has some edge, since it allows the user to implement +segmentation if needed and avail oneself to its advantages. + + +Paging + + The MMUs of both systems feature paged virtual memory management. +The 80486 offers a single standard page size of 4 kbytes. This page size +is implemented in many other systems. With a 4-kbyte page size, one can +arrange an address mapping where the page directory and the page tables also +have the standard page size of 4 kbytes (1024 = 2^10 entries, 4 bytes each). +Thus, the page directory and the page tables can be treated as entire pages +and placed within page frames in the memory. This results in reduced +complexity in the MMU hardware and in the OS software, one of whose tasks is +to support the management of virtual memory. The MC68040 offers two page +sizes, selectable by the user: 4 kbytes and 8 kbytes. This tends to +complicate the MMU logic and the OS. It is a good thing that Motorola got +rid of the other page size options available with its MC68851 paged MMU: +8 sizes ranging from 256 bytes to 32 kbytes, stepped by a factor of 2. On the +other hand, the 8-kbyte per page option could be useful to a programmer dealing +with large modules of code exceeding 4 kbytes. + + +TLB (or ATC) Size + + The 80486 MMU has a 32-entry TLB. With a 4-kbyte page it covers +32 x 4 kbytes = 128 kbytes of memory. The MC68040 offers much more. The TLB +is called address translation cache (ATC) by Motorola, but it does the same: +it translates virtual into physical addresses. The name given by Motorola is +simpler to perceive, although the TLB term is predominately used in the +computer literature. Each of the two MC68040 MMUs has a 64-entry ATC, for a +total of 128 entries on the chip. For a 4-kbyte page, a total of 128 x 4 +kbytes = 512 kbytes of memory is covered (4 times that of the 80486), and for +an 8-kbyte page, 1 Mbyte (8 times that of 80486). In this case, a strong +advantage of the MC68040 is obvious. Since the ATCs encompass much more +memory, the ATC miss probability is considerably smaller. Thus, less time +will be wasted in accessing page tables in memory, resulting in faster overall +operation. + + +Levels of Protection + + The 80486 offers four levels of protection, while the MC68040 has only +two - the supervisor and user, as does the whole M68000 family. While the +protection mechanism of the 80486 is much more sophisticated and, with the +segmentation encapsulation of information, offers more reliable protection, +it also results in more complicated on-chip logic. More time is taken up with +protection checks on the 80486. + + +Instruction Pipeline Stages + + The 80486 instruction pipeline has five stages, while that of the +MC68040 has six. This means that the 80486 pipeline can handle five +instructions simultaneously and the MC68040 can handle six. This certainly +gives an edge in favor of the MC68040, although its MMU-cache-internal buses +duality is a much stronger contributor to its enhanced speed of operation. +The above comments are valid if the instructions are executed sequentially, +without any taken branches. In the case of the taken branch, the subsequent +prefetched instructions are flushed from the pipeline hardware. Neither +the 80486 nor the MC68040 employ the delayed branch feature, as do most of +the RISC-type systems. The MC68040 designers have investigated the possibilityof featuring a delayed branch or other techniques to alleviate the problem of +lost cycles in case of a flushed pipeline. After a number of simulations, +they came to the conclusion that the gain in performance was not worth the +extra hardware expenditure incurred in the implementation of any of the methods +considered. In RISC-type systems, on the other hand, due to reduced control +circuitry there is extra space for features such as the delayed branch which +alleviates the pipeline management problem in case of a taken branch. Indeed, +Intel's RISC 80860 and Motorola's RISC M88000 both implement the delayed branch +technique as an option, selectable by the user. + + +Performance Benchmarks + + +Dhrystone Benchmark Version 2.1 (Integer Performance Test -- ALU) +----------------------------------------------------------------------------- + System Results - Kdhrystones/s Relative +----------------------------------------------------------------------------- +VAX 11/780 1.6 1.0 +Motorola MC68030 (50 Mhz,1ws) 20.0 12.5 +Intel 80486 (25 Mhz) 24.0 15.0 +SPARC (25 Mhz) 27.0 16.8 +Motorola M88000 (20 Mhz) 33.3 20.1 +MIPS M/2000, R3000 (25 Mhz) 39.4 23.8 +Motorola MC68040 (25 Mhz) 40.0 24.3 +Intel 80860 (33.3 Mhz) 67.3 40.6 +----------------------------------------------------------------------------- + + + As one can see, the MC68040 Dhrystone integer performance considerably +exceeds that of the 80486.

It should also be noted that both the MC68040 and +80486 have an on-chip cache, while the M88000 cache is on a separate CMMU +chip (MC88200). + + + It should be noted that all of the above comparisons were conducted +with artificial benchmark programs such as Dhrystone. It is quite possible +that for some "real-life" programs the performance ordering might be quite +different. It is no accident that when company A conducts benchmark +experiments, its products come out ahead of others. It is quite possible +that when another company, say B, publishes its own benchmark results, the +performance ordering may look different. Therefore, the sample of benchmark +comparison results presented should be regarded as a tentative indication. +They are certainly not conclusive. + <*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*> + <*> <*> + <*> >>> THIS TEXTFILE PASSED THROUGH IMAGINE BBS ++46-42-135505 <<< <*> + <*> """"""""""""""""""""""""""""""""""""""""""""""""""""""" <*> + <*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*><*> + <úúSúCúOúOúPúEúXúúúSúWúEúDúEúNúúúHúEúAúDúQúUúAúRúTúEúRúú> diff --git a/textfiles.com/computers/4chan8bi.asc b/textfiles.com/computers/4chan8bi.asc new file mode 100644 index 00000000..ff637269 --- /dev/null +++ b/textfiles.com/computers/4chan8bi.asc @@ -0,0 +1,252 @@ +From: fdeck@sleepy.helios.nd.edu (francis deck) +Subject: CHEAP 8-BIT ADC FOR IBM PC + +PLANS FOR A 4-CHANNEL 8-BIT ANALOG-TO-DIGITAL CONVERTER FOR PC + + Francis J. Deck + fdeck@grumpy.helios.nd.edu + +This is an extremely simple ADC for the PC. It connects to the parallel +printer port, and runs from a 9V battery. All parts are available from +Digi-Key Corporation (1-800-DIGI-KEY), and cost is under $20, including box! +Input voltage range is 0 to 5 V. Driver software is in Turbo Pascal.

It is not +intended to train or encourage novices to attempt service or modifications +to expensive appliances. It is especially not intended to encourage +unqualified personnel to tamper with dangerous appliances such as monitors, +power supplies and other devices which contain vacuum tubes, live mains or +high-tension rails, or other hazardous areas. Any such work carried out is +done at the reader's own risk and the author accepts no reponsibility for +damage to property or person which occurs as a result of attempting any of +the procedures described herein. + Having said that, I can vouch for the workability of the +modifications listed here. I have personally performed them all myself on my +own machines (this is, after all, a chronicle of my own experiences, chopped +up under suitable headings for your convenience). With regards to the service +information, whilst I have described problems and the solution(s) I found, +keep in mind that this is rather like a doctor prescribing medication over +the telephone or from an encyclopaedia. What I mean by this statement is that +different problems may well cause the same symptoms; to take a trivial +example, if you turn your monitor on and nothing happens, perhaps the fuse is +blown, but on the other hand, perhaps it is not plugged in, or perhaps there +is a more sinister fault in the power supply section. For this reason, I +suggest you use the service information as a very vague guide ONLY. Remember; +it is very rare to find two machines which are exactly the same inside, and +so what I have found to be a suitable solution to a given fault may be +totally inappropriate to your situation. + + -=<* The Commodore Amiga 500 *>=- + +i. Serial Killer +---------------- +Problems with Amiga serial ports generally fall into three categories; problems +with the flow control lines, problems with the actual data transmission lines, +and problems with the line level (caused by faulty line driver chips). The +first two can be relatively costly to repair, due to Commodore's monopoly on +the CIA and Paula chips, so I advise exploring the line driver section of the +circuit before rushing out to buy new Paulas or CIAs. + Faults in the line driver chips (MC1488 and MC1489, U38 and U39 +respectively in the schematic on page F-7 of the book 'Introduction to the +Commodore Amiga 500') are typified by either total loss of transmission, total +loss of reception, or both. If you look at the flow control lines, (CTS and +RTS), you usually see that these lines are behaving normally (exactly why +these lines are rarely affected is a mystery to me); if not, then you probably +have a faulty CIA. Since the 1488 and 1489 only cost around A$1.00 each, +depending on your source, it is well worth replacing these chips before you +investigate Paula. Unfortunately, they are not socketed so you will have to +desolder them (see "Desoldering Small IC's" below). When you have the chips +out, put in a couple of sockets to facilitate later repairs. + If, after replacing the 148x's, you still experience problems, it is +time to look further. If you have suitable software, you can check whether the +problem lies in the flow control lines (in which case you have a damaged even +CIA, U8) or in the data lines (in which case you have a damaged Paula). If you +do not have, or are unable to interpret the results of, this software, you can +make use of an old Amiga-tech wrinkle; exchange the CIA chips and see if your +fault clears up. If it does, then ten to one the problem is in the CIA which +started out as U8; if the problem persists, then it is most likely a Paula +fault. + +ii. Floppy Hassles +------------------ +In my life I have opened at least 40 Amiga 500's and have NEVER seen two which +have the same make and model of internal floppy. It seems that Commodore +change their suppliers (and also the colors of the LEDs on the keyboard) on a +weekly basis. Let's see.. three possible LED colors (red, green, yellow), +three LEDs on the keyboard, four floppy manufacturers (Sankyo, Chinon, +Panasonic, Sony), two different styles of head connector (one film connector +per head or one wide film connector servicing both heads), helical screw or +belt-drive head carriage mechanisms.. that makes 144 possible configurations +already. For this reason it is not possible to give specific "look-to-the-left- +of-the-large-chip" directions, and I can only state a couple of possible faults +and their possible causes : + +* Floppy refuses to acknowledge disk insert +Probably caused by a defective odd CIA (U7). Try switching the CIAs over. Also +check that the switches at the front of the drive travel freely up and down. +Verify that the pads to which the switch assembly is connected have not flaked +off the board (this can be caused by rough disk insertion). + +* Floppy will not read disks formatted in other drives +The head alignment is faulty. There is a method of adjusting it without +special tools and measurement devices, but it requires considerable patience +and one of the X-Copy series of programs. The method is as follows : +- Format a disk in a working drive. +- Open your machine (or external drive). Remove the cover from the drive unit +(it is usually held on by one screw on either side and another on top at the +back). Locate the track zero sensor and loosen the screw which holds it in +position. Load X-Copy and select the Toolkit option CHECKDISK. +- You must now align the lower head. This can be accomplished by moving the +track zero sensor a little, then checking the disk, and repeating this until +you find a position in which the drive will read the lower side of the disk. +When this is done, tighten the screw which holds the track zero sensor, to +stop it shifting. If you have any Lok-Tite, a drop of that on the screw is +advisable. +- You must now align the upper head. Loosen the two screws which hold it to +the head carriage assembly (Do NOT remove these screws, unless you relish the +idea of going over the floor with a metal detector looking for small springs). +Adjust the upper head by eye until it appears to be exactly over the lower +head. Now repeat the above trial-and-error process, tweaking the upper head +around until you find a workable position. Tighten the screws, replace the +cover and reassemble. + If the above procedure sounds rigmarolish and uncertain, it is ! But +I have successfully performed it on a number of Amiga and PC 3.5" drives. And +I have never had a failure with it. + +iii. Caps Lock Chaos +-------------------- +Many Amiga owners will know, to their detriment, that occasionally the Caps +Lock light will start blinking and the keyboard will lock up. This is caused +by the microprocessor in the keyboard detecting a keyboard fault. I first +noticed this fault when our school Amiga room (two rev. 5a A500's) acquired an +autofire joystick, a Quickshot IIb I think. When switched to autofire mode, +this joystick would periodically jam the keyboard. If you have recently +acquired an autofire joystick, you should investigate whether turning it off +during boot fixes the problem. Otherwise, you can try the old "Atari Twist", +ie pick up your machine in both hands and twist it. This is basically +equivalent to reseating the chips on the motherboard; if you have a spare +moment, I suggest you actually open the machine up and manually reseat them. + +iv. Bulimia of the Agnus +------------------------ +iv-1. What is the 1Mb Agnus ? +----------------------------- +The 1Mb Agnus (variously known as the Obese Agnus or Fatter Agnus), Commodore +part 8372a or 318069-02, is the relatively new Agnus which is capable of +addressing 1Mb of chip-RAM. This allows you to have twice the amount of +sampled music, screens, and other custom-chip data in memory simultaneously. +It also has the desirable effect of letting you run things like Deluxe Paint +in 16-color 640x512 (or 640x400, NTSC users) mode, without having to +disconnect external drives, close down WorkBench screens and the like. For +A-Max users, installing the new Agnus and configuring it to 1Mb chip-RAM mode +will also increase A-Max compatibility. If you have more than 1Mb of RAM, then +it will make A-Max virtually 100% identical to a Mac Plus, memory-map-wise. +NOTE WELL : This modification requires 1Mb of RAM to be visible ! + +Commodore, not wishing to make two chips where one will do, is now shipping +the 8372a in most (nearly all Rev. 6a) A500's, without telling anybody. In +these machines, the extra chip-RAM capability has been disabled so that if you +connect an A501, it will still think it is "slow" [see below] RAM. + +iv-2. An Aside on Memory Speeds +------------------------------- +The Amiga has *three* types of RAM. Chip-RAM, Fast-RAM and "Slow"-RAM. +Contrary to what many people assert, RAM at $C00000 (the default location of +the A501 expander, and the second 512K of RAM in A2000's) is NOT fast-RAM, +even though the system reports it as such. Because this RAM is refreshed and +accessed via Agnus, it is affected by buss contention in just the same way as +chip-RAM. It is simply a dead area in RAM which is not accessed by the custom +chips and which is not faster than chip-RAM. Moving this RAM to $80000 (which +is what you do to enable 1Mb chip-RAM) will have no effect on machine speed at +all. + +iv-3. Compatibility +------------------- +To date (20-Oct-91, 18:11EST) I have personally tested at least 400 pieces of +software with the new Agnus. I have found three programs which do not work : +* Double Dragon II (Completely screwed up) +* VideoFX 3D (Again, completely useless) +* Impossible Mission II (This game requires memory at $C00000. It does not +mind the Agnus, but if you want to run it you must drop back to +512K chip/512K slow mode. Lousy AllocAbs() programmer !) +In addition, Dragon Ninja thinks you are running on a 512K machine and will +not play in-game music. Again, this can be rectified by switching into 512K +chip/512K slow mode. Some other games also think they are running on a 512K +machine, notably TechnoCop and R-Type, but this is of no real consequence. + +iv-4. Identifying the Version of your A500 +------------------------------------------ +There are several versions of the A500 out there. I have only tried fitting +the new Agnus to the following : + a. The Revision 5 board shipped until early 1989 + b. The new Revision 6a board supplied from May (?) 1989 onwards +The way to identify your machine type is to check the expansion port which +lurks under a plastic cover on the left-hand side of the computer. The Rev. 5 +machine has a very fat strip (double width) at the back of the connector; the +Rev. 6a board has two normal-width strips instead. + +iv-5. Installing the 8372a to Revision 5 A500's +----------------------------------------------- +1. Remove the 8371 from its socket. If you are an NTSC user who does not wish +to use the PAL mode, go to step 3. +2. Pin 41 of the new Agnus controls whether the machine starts up in PAL or +NTSC modes. When it is tied low (to ground), the machine boots in NTSC mode. +When the line is tied high or left floating (ie unconnected), it boots into +PAL mode. On the Rev. 5 board, pin 41 is connected to ground by tracks on BOTH +sides of the board, making it virtually impossible to cut the track without +desoldering the socket. This means if you just plug in the new Agnus, you will +be locked in NTSC mode !! There are a couple of ways to go about circumventing +this problem; I will detail here the one I undertook on my own Rev. 5 board. I +will assume you want to install some sort of switch to toggle PAL/NTSC mode. +If you only want to run in PAL mode, you can simply bend out pin 41 of the +Agnus socket (don't bend the pin on the chip) to prevent it from making +contact with Agnus. If you do this, proceed to step 3. Otherwise, get yourself +an SPDT or SPST toggle switch and two lengths of telephone (or other thin, +stiff single-core wire). Solder wires to the switch : + + +---+ + To a convenient ground--+-o | BACK VIEW OF SWITCH + +--------+-o | When held as shown, UP=PAL, DOWN=NTSC. + | | o | + | +---+ + Uninsulated --> | | <-- This side is insulated + \-/ <-- Fold the wire thru 180 degrees + +3. Insert the new Agnus. If installing the switch, you should now poke the +loose end of wire (see above) from the switch into pin 41 of the socket so +that the bare copper side touches the pin on the chip and the insulated side +touches the pin on the socket. In order to fit the wire down the hole you may +find it necessary to bend out or remove entirely [Not recommended !] the pin +on the socket. Secure the wire with a tiny drop of cyanoacrylate adhesive. + +4. If you wish to install a memory mode switch, go to step 5. Otherwise, +locate JP2 (between 68000 and ROM). This consists of three pads. The center +and lower pads are joined by a thin track. Cut this track and place a drop of +solder between the center and upper pads. Now locate the _EXRAM line coming +from the A501 port (it comes from pin #32 and runs on the upper side of the +motherboard parallel to the A501 connector). Cut this line. You have now +completed the installation procedure. + +5. Complicated. Locate JP2 and cut the track which joins the center and lower +pads.

Installing the 8372a to Revision 6a A500's +------------------------------------------------ +1. Remove the 8371 from its socket. Insert the new 8372a. NTSC users who do +not wish to use the PAL mode should go to step 3. When installing the new +Agnus, note that on the 6a board, the Agnus socket has been rotated 90 degrees +anti-clockwise from the orientation on the revision 5 board. For this reason, +plugging in the Agnus correctly is no longer an intuitive operation ! +2. JP4 controls PAL/NTSC video mode. If you are in North America or Hong Kong +or anywhere else the National Television Standards Committee TV format is +used, this should be bridged by a track or a blob of solder. If you are in +Australia, Europe or anywhere else the Phase-Alternated Linescan TV format is +used, this jumper should be cut open. If you wish to install a switch, then +simply connect it across the two pads of the jumper. +3. Cut the track joining the center and upper pads of JP2, and the track +joining the center and upper pads of JP7a. (JP2 is between the CPU and the ROM +and JP7a is just to the left of the A501 connector). If you wish to install a +memory switch, proceed to step 4 otherwise solder the center and lower pads of +JP2 together. You have now completed the installation procedure. +4. Connect a DPDT switch as follows : + + +-----+ BACK VIEW OF SWITCH +Upper pad of JP2 --+-o o | When held as shown, UP=512K CHIP, DOWN=1M CHIP +Center pad of JP2 -+-o o-+-- Center pad of JP7a +Lower pad of JP2 --+-o o-+-- Upper pad of JP7a + +-----+ +You have now completed the installation procedure. + +v.

Hol(e)y, Hol(e)y, Hol(e)y +----------------------------- +Owners of Rev. 6a A500's will notice that they only have 4 RAM chips as +opposed to the 16 in the Rev. 5 and earlier machines. They will also note that +in between the RAM chips are empty sets of holes which look like something +ought to go into them. + Firstly, fear not - the reason you have a quarter the number of RAM +chips as older machines is that the 6a uses 44256 4-bit x 256K chips which are +four times as large as the 41256 1-bit x 256K chips used in the 5 and earlier +revisions. All the modern Amiga memory hardware (except possibly the A501) +uses these larger chips because they are slightly cheaper on a dollar-per- +megabyte basis. For example, the older Series I A590 hard drives use the +41256, and they will accept up to 2Mb. The new Series II A590's use the 44256 +(and consequently have enough space to fit 8Mb of RAM). + But, back to those extra holes. They are indeed designed to accept +something; viz, another set of four 44256's to take your machine up to 1Mb +without having to buy an A501 or other expander (this is particularly useful +if you have a memory expansion which uses the A501 slot, and you want to have +1Mb chip-RAM). If you want to install your own RAM there, you should do as +follows : Purchase four 20-pin IC sockets (preferably machined-pin). Make sure +you have a solder-sniffer. Now look at those holes and you will see that they +are clogged by solder (this is due to the way the boards are soldered; the +process covers all exposed copper areas with solder). You must clean this +solder out by heating the board from one side and sniffing the solder out on +the other (or blowing the solder through; if you choose this method, make sure +to remove all the little splashes of solder from the board and your lap). When +you have cleaned out all the holes, solder in the sockets. Now plug in four +44256 chips and you have 1Mb of memory for slightly less than the cost of an +A501 (in Australia, the difference is roughly A$20). + With respect to the speed of RAM chips required, I use 150ns chips +with no problems at all; however, I suspect that Commodore would recommend +100ns devices. The price difference is minimal so you may as well buy 100ns +chips so that if you ever buy a series II A590, you can shift the chips over +and have 100%-guaranteed-not-to-overheat fast-RAM. + +vii. 1Mb of Motherboard Memory on the Rev. 5 +-------------------------------------------- +It is possible to install 1Mb of RAM onto the revision 5 motherboard. However, +this modification is flaky at best and I cannot recommend it (having tried it +in a moment of sheer boredom). Also note that I could *not* get this extra +memory to be mapped at $C00000 (the computer would only recognise it if I had +JP2 set to map the A501 at $80000); which means that it is only of potential +interest to owners of the 1MB Agnus. (This failure to work as $C0 RAM may well +have been due to some stupid omission on my part). + I will deliberately be vague because this is not a trivial +modification. If you are unable to work out what to do with confidence, you do +not have enough knowledge to perform the mod. + The procedure can be summarised as follows: Take sixteen 41256 RAM +chips (for speed information, see the end of subsection vi. above). Bend the +refresh address strobe pins (_RAS, pin 4) on all the chips up and over so that +it is well clear of the other pins and easily accessible from the top of the +chip. Bend in all the other pins a little. Now, piggyback the new chips on top +of the existing RAM, making sure to install them in the same orientation as +the original chips. It is not possible to reach all the pins to solder them, +so you will have to content yourself with only soldering the corner pins. +Solder wires from the bent-up _RAS pins to pin #38 of the A501 port (or any +convenient take-off point of this signal). You should now have 1Mb of RAM. (If +you want to try using it as $C00000 RAM, you should ground the _EXRAM pin, pin +#32, of the A501 port. I had no success with this). This mod sounds all very +well, but in the current climate it may be slightly cheaper to buy a +secondhand A501 than to buy 41256 chips. In addition, due to the precarious +hold the piggybacked chips have on the originals (because there isn't enough +room to solder all of the pins down), the mod is sensitive to shock; if you +tap the table, you can sometimes guru the machine. For this reason, this is a +"possible but ill-advised" modification. + +viii. Double Trouble +-------------------- +The hack to accelerate your Amiga to 14MHz has been published in countless +articles, but I may as well include a brief description of it here. The hack +involves removing the original 68000 from your Amiga and substituting a +version rated at 16MHz (confusingly called the 68000P-12; the Motorola chips +have "16MHz" stamped on them, but the SGS-Thompson clones do not). The clock +pin is bent out and soldered to the output of a divide-by-2 counter whose +input is connected to the base 28MHz clock. THIS MODIFICATION SHOULD BE +INSTALLED WITH A SWITCH !! If not, you WILL (not may) find that some games +will refuse to load because they use timing-dependent loaders. + Aside from the problem mentioned above, the only compatibility +down-side to this modification is that some floppy drives will not handle the +increased step rate. If you find that your drives give read/write errors at +the high speed, you can either replace them or run a program called "DFDelay" +to slow down the step rate. (If df0: will not work, you have a problem. Try +swapping df1: for df0: - to do which you will need a Commodore df1:. The +mechanisms used in the old A1010 drives are EXTREMELY reliable and much +quieter than the new rubbishy things; if you have an A1010, you can be fairly +certain that it will support the new speed). + To perform the mod, remove your old 68000 and embed it in a perspex +block for future reference. Now rig half of a 74S74 dual D bistable as a +divide-by-2 counter. Connect the input of this to a convenient take-off point +of the 28MHz clock line on the motherboard (I use pin #34 of Agnus, but +anywhere will do). Now bend out pin 15 of the new CPU and solder a wire to +this pin. Take a piece of stiff telephone wire, strip approx. 5mm of +insulation from one end, and stick this end down pin 15 of the 68000 socket. +Insert the new CPU in the socket and verify that pin 15 is well clear of the +wire in the socket. Now wire a SPDT switch as follows : + + BACK VIEW + +---+ When held as shown UP=7.14MHz, + To output of divide-by-2 counter -+-o | DOWN=14.28MHz + To pin 15 of 68000 -+-o | + To wire in pin 15 of 68000 socket -+-o | + +---+ + +The 74S74 should be mounted somewhere convenient; I break off all the unused +pins, bend the remaining pins out, and stick the chip on top of one of the +data path IC's; this has the advantage of allowing me to take power directly +off the existing components rather than stringing yet another pair of wires +through the machine. + If you only have chip and/or slow memory (see subsubsection iv-2.) +then your machine will run at approximately 150% normal speed (on +CPU-intensive operations; DMA rates will be unchanged). If you have true +fast-RAM then code running from fast-RAM will execute at close to 200% of +normal speed. Try placing a large perpective brush with anti-aliasing HIGH +in DeluxePaint III (or IV !) and you will see the speed increase. + +ix. The Numbers Game +-------------------- +This is how PLCC chips are numbered (using Agnus as an example) : + + 1 1 8 8 8 8 8 7 7 7 7 7 + 1 0 9 8 7 6 5 4 3 2 1 4 3 2 1 0 9 8 7 6 5 + BEVELED CORNER | | | | | | | | | | | | | | | | | | | | | + /-------------------------------------------| + 12 -| o |- 74 + 13 -| |- 73 + 14 -| |- 72 + 15 -| |- 71 + 16 -| |- 70 + 17 -| |- 69 + 18 -| |- 68 + 19 -| |- 67 + 20 -| 8372A |- 66 + 21 -| |- 65 + 22 -| |- 64 + 23 -| TOP VIEW |- 63 + 24 -| |- 62 + 25 -| |- 61 + 26 -| |- 60 + 27 -| |- 59 + 28 -| |- 58 + 29 -| |- 57 + 30 -| |- 56 + 31 -| |- 55 + 32 -| |- 54 + |____________________________________________| + | | | | | | | | | | | | | | | | | | | | | + 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 4 5 5 5 5 + 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 + +x. A Change Of Face +------------------- +Installing the ECS Denise is simplicity itself. Simply remove the old Denise +and plug the new one straight in. Note that to use the new video modes, you +require the 1Mb Agnus (not necessarily in 1Mb chip-RAM mode, though). By +installing the new Denise, you also eliminate the annoying video glitches +which occur in NTSC mode when using the new Agnus with the old Denise. + +xi. Snap, Crackle and Pop +------------------------- +[For non-Australians, the above is the slogan a local cereal company uses to +advertise a tasteless soggy mess called Rice Bubbles]. + Symptom : Your monitor produces snapping or popping noises, and +sometimes goes unaccountably blank after being switched on for a while. + I have no idea why this problem seems to affect Commodore monitors so +badly. It is caused by arcing of the EHT rail (around 14kV, from memory) to +lower-voltage areas of the set. Initial treatment is to turn off the monitor, +leave it for a couple of days (to allow capacitors to discharge), and then to +remove every last speck of dust from the inside. This usually works. + If it does not, however, sterner measures are called for. Open your +monitor and (here comes the dangerous part) leave it running, open, for a few +hours. If you actively work against Murphy's Law by watching it from behind +something or inside something, where the monitor can't see you, you MAY +eventually be lucky enough to actually catch it in the act of arcing. Mark the +place with a spirit pen and spray on some anti-gaussing compound. (This stuff +has a very high dielectric constant and hence helps to prevent arcs). + +xii. Yo Ho Ho And A Packet Of Disks +----------------------------------- +I sometimes describe A-Max as the only useful productivity tool for the Amiga; +Mac owners will agree with me when I say that Macintosh applications are +incomparably better than their Amiga counterparts. However, due to suppression +of the source of 128K ROMs by a certain computer mega-corporation named after +a piece of dead plant, the future of this marvellous product looks slightly +less certain than Melbourne hosting the 1996 Olympic Games (grin). + There exists a software patch which will allow you to [illegally] run +the emulator using a ROM image file on disk; however, if you wish to use a Mac +drive with the A-Max cartridge, you must have ROMs or EPROMs in the ROM +sockets. Problem ? No. Simply insert two blank 27512 64K x 8 EPROMs in the ROM +sockets. + +NB: The above procedure is wholly illegal and the author is not explicitly +condoning nor advocating the practise. I personally own original Apple 128K +ROMs (purchased before the great ROM drought). The above information is +supplied for interest's sake only. + + -=<* The 80x86-Based PC/XT/AT-Compatible *>=- + +i. Tools of the Trade +--------------------- +Since I come across many cards and peripherals of doubtful functionality, I +have invested in a 10MHz 286 motherboard with just enough RAM to get started, +plus a $20 Hercules card to run diagnostic programs. This is mounted in an +ancient XT casing, with an equally ancient 150W power supply. The total cost +of this system was about $150, and it allows me to test all XT and AT cards +(not EISA cards, but then I have no EISA-buss machines anyway !), drives and +so on. If you expect to be buying/selling many secondhand cards, drives, SIPPs +and so on, I heartily recommend buying such a system, unless you are game +enough to risk your "real" system by putting possibly defective cards in it. + +ii. The Heat Is On +------------------ +In many clone machines, particularly 16MHz or faster 286's which use the AMD +80286 rather than the Intel original, the CPU becomes extremely warm, too hot +to touch with the hand. For example, I have a 16MHz Acer motherboard which +uses an AMD 80286-16 processor, and after 25 minutes of operation at turbo +speed, the processor is far too hot to be touched for more than half a second. +This kind of heating is undesirable in that it shortens the chip life and, +more importantly, may lead to sudden crashes if the chip undergoes thermal +shutdown. (The so-called XT-286's, XT-class machines with 80286 processors, +are very susceptible to this problem). If your machine has this undesirable +property, you should consider attaching some sort of heatsink to the CPU. An +extra fan in the casing is also an option, though I find them to be relatively +ineffective for this task. + You can also try replacing the CPU with an original Intel chip. For +some reason, the Intel line stays a lot cooler than the AMD line in general. + +iii. Sudden Death +----------------- +Scenario : You are working on an important document under an operating system +known to be bug-free (aren't fairy-tales wonderful ?). You leave the keyboard +to take your ten-minutes-per-hour anti-RSI coffee break. You return (having +neglected to save your work), you press a few keys... and nothing happens. +Your document is there on the screen, but the program has halted. + The above is quite often caused by overheating problems (see +subsection ii). It is also sometimes caused by dirty or otherwise imperfect +connections between cards or chips and their sockets. If your machine is more +than 2 years old, it may well be that your sockets are becoming dirty. (An +interesting anecdote springs to mind about a small LAN of XT-class machines, +all of which seemed to fail simultaneously. It turned out that the network +cards used single-wipe sockets which degraded much faster than the dual-wipe +sockets used on the motherboards, and occasionally the fileserver would start +to send out a packet, but would only manage to send part of the header before +the faulty network card corrupted the transfer. Because of a "feature" in the +network software, all the machines on the LAN stopped operations while waiting +for an ID sequence to indicate the machine the corrupted packet was destined +for. This looked exactly like a simultaneous crash on twenty machines and had +the serviceperson (erm, me) puzzled for quite a few days). + The immediate cure for this sort of problem is to pull out all your +cards, clean the connectors with an ink eraser (pencil erasers are not +abrasive enough), remove the fragments of eraser and reinsert the cards. You +can also push down on all the socketed chips to reseat them. + Oh yes. The above problem can also be caused by viruses. Use McAfee +Associates' SCAN (and if necessary CLEAN) programs to detect and kill these. + +iv. Overworked FPU's +-------------------- +Due to the large price discrepancy between the different speed ratings of +floating-point coprocessors, there is a strong temptation to buy (say) a 25MHz +387 for your 33MHz 386. The chances are good that such an arrangement will in +fact work, however note that the power dissipation of the FPU will be +increased. In simple terms, it will get hot. For this reason, you should +always look for ceramic-bodied chips, since they can dissipate MUCH more heat +than plastic-bodied devices. And whenever possible, run in non-turbo mode. + +v. Hot-Rodding, Across the Universe +----------------------------------- +It is relatively common knowledge nowadays that it is quite possible to +hot-rod a 16MHz machine to 20MHz or a 33MHz machine to 40-50MHz. This +naturally carries with it the same overheating problems mentioned in +subsection iv above. However, if you are determined to undertake such a +modification, there are a couple of pieces of information you may find useful: +- For 80286 and 80386 machines, you will need a crystal or oscillator can +(make sure you know which you need) which is TWICE the frequency you want your +machine to run at. +- The crystal to replace is the one rated at TWICE the listed speed of your +motherboard (ie on a 16MHz board, there will be a 32MHz crystal). Do not be +led astray by the I/O clock crystal(s) ! +- It is good practice to place a socket on the motherboard where you removed +the old crystal, so that if you ever have to sell your machine you can pop in +the original speed of crystal and cover up your tracks. + Note that I have never performed this type of enhancement to 80386 +machines; however, this document is being typed on an 80286 which I hot-rodded +from 12MHz to 16MHz. + +vi. Hacked Reset Switches +------------------------- +Most 286/386/486 motherboards (all I have ever seen) come with a reset switch +connection built-in; many XT motherboards do not. Consequently there have been +a number of postings to USENET describing how to add a pushbutton to the +_RESET line of the CPU. I find it rather amusing that several such founts of +wisdom advise the installation of a pullup resistor "to make sure the line +goes high again after the button is released". Interesting. Does this mean +that when you turn on your machine, you only have a 50/50 chance that the +_RESET line will be high enough to let the CPU start ? Of course not. The +designers already put in a pullup resistor, so there is absolutely no need to +put in another one. Just connect a normally open pushbutton between the _RESET +pin of the CPU and any convenient signal ground. + +vii. Tearing Your Hair +---------------------- +Scenario : Your favorite machine, with SoundBlaster, LAN, VGA, Hercules, Voice +Master, two serial and one multi I/O cards goes down. You don't know where to +start. + The first thing to do in such cases is to remove every card except the +display adaptor and the floppy controller (if this is integrated with the hard +disk controller then both will have to stay). You should now simply keep +adding cards until the machine no longer starts up (assuming it starts up in +its minimal configuration). Whilst this may sound obvious, you would be amazed +by the number of people who leave all their cards in and just poke about with +the jumper settings. + +viii. Mix And Match +------------------- +It is often very convenient to have two monitors connected to the one machine. +(I have both VGA and Hercules cards in my "useful" machines). However, not all +display adapters can be mixed together in the one machine (due to memory +conflicts). Below is a table of the allowable configurations; a star indicates +"allowable" and a period (full stop) indicates an illegal combination. + + with MDA CGA EGA MCGA VGA + MDA . * * * * + CGA * . * . . + EGA * * . . . + MCGA * . . . . + VGA * . . . . + +For the purposes of display mixing, an MDA (mono 80x25 text only) is identical +to a Hercules Graphics Card (720x348 mono graphics). Note that if you have a +VGA card as one of your displays (the most common configuration is VGA + MDA +or Hercules), your VGA card will no longer be able to emulate Hercules modes. +(If you load up the extended-mode-handler program supplied with most SVGA +cards, you will be told that the card cannot be switched into mono mode). Note +the possible pitfall with Hercules cards; most of them contain a parallel +port, usually switchable from address 3BC to address 378. If you already have +a parallel port mapped at this address, strange errors will crop up. (Also +note that if you have parallel ports at 378 and/or 278, and the Herc parallel +port is at 3BC, the Herc card will become LPT1: - this may necessitate some +switching of cables). If possible, disable the onboard parallel port, or map +it to an unused port address. + One final note on the subject of video conflicts; a number of clone +companies have released so-called "color Hercules" cards, which support both +the Hercules and CGA standards. These cards will not co-reside with any other +video card. + +ix. Expanding SVGA Cards +------------------------ +Many people ask, "Can I expand my SVGA card ?". In most cases, the answer is +no. However, occasionally one runs across cards which have sockets for extra +RAM. The two examples of this which I have seen are Tseng Laboratories SVGA +cards (mine came with 512K and space for an extra 512K), and Trident cards +(again, mine came with 512K, but had sockets for the extra RAM). In such +cases, installing the extra memory is simply a matter of purchasing the +requisite RAM chips (usually 44256; however, some older cards will use 4464 +or 41256 chips), and installing them in the empty sockets on the card. Before +you spend the money on this, however, consider - do you really need the extra +memory ? In the vast majority of SVGA cards, adding the extra RAM only allows +you to use ONE extra mode, viz. 1024x768x256. This mode is not really useful +unless it is un-interlaced (stare at an interlaced screen for a few hours and +you will understand why !). Also, on monitors coarser than 0.28" dot pitch, +this mode looks EXTREMELY fuzzy, and on some monitors it is not even +displayed properly (the edges of the screen are compressed). Although my +cards support this mode, I always use 640x480x256 as my maximum screen +resolution (except when viewing very large GIFs, eg the 1152x900 pictures +designed for and/or digitized on Suns). + A final note : I have yet to see a card which was supplied with 256K +which is expandable. Most of these cards were very early models which used +older (true VGA) chipsets incompatible with the newer de facto video +standards. + +x. To BIOS or not to BIOS ? +--------------------------- +THe question is often asked, "Which BIOS is best ?". One would imagine that +the best BIOS should be an original IBM chip; however, since most software is +developed on clones (I wonder how many people have seen a real IBM recently - +I haven't seen anything more recent than an original 5-slot PC, although I do +know of the PS/2, a 286 machine. Does IBM in fact make a 386 ?), a machine +with a "real" BIOS is not necessarily more compatible than a clone. So the +choice of BIOS boils down to personal preference. I personally own AMI 286 and +386 BIOSs, and Award 386 BIOS, and I have used Phoenix 286 and Award 286 BIOS. +Out of these, I strongly recommend the AMI (American Megatrends) BIOS because +it seems a lot more sensibly designed than the Award or Phoenix programs. For +example, the AMI 386 BIOS allows you to set up a whole lot of low-level +chipset parameters related to memory speed and setup, whilst the Award only +allows you to set drive and display types. Also, if you have been toying with +the XCMOS settings and have managed to make your computer non-functional, if +you have the AMI BIOS, you simply hold down Insert while pressing the reset +button, and the XCMOS settings will be set to default values, unlocking your +machine. With the Award BIOS, I had a machine with Hercules and VGA cards, but +no mono monitor, and I accidentally set the display type to "MONO", meaning +that the machine booted on the Herc card where I couldn't see anything.. in +order to get the machine usable again I had to open it and unplug the Hercules +card to force the BIOS to return to the VGA/EGA display setting. Annoying, +especially since the machine in question was the bottom (Murphy again !) in a +stack of three PCs with a monitor on top, all on a very crowded desk. + NB: Since the BIOS is resident on a standard EPROM, it is quite +possible to copy it using an EPROM reader/burner and a blank EPROM of the same +type. However, the astute will notice that there are *two* chips in the +machine with little holographic stickers; the BIOS and the keyboard +controller. I have never had occasion to try pirating BIOSs, but I doubt that +BIOS A will work with keyboard controller B. They definitely "know" about one +another, because when you boot a slow AMI machine, you see a serial number of +the format --K (a pause while the keyboard is accessed), +then another digit indicating the keyboard controller version. + + -=<* General Information *>=- + +i. Desoldering Small IC's (Less than 40 pins) +--------------------------------------------- +Small chips can be fairly easily desoldered by inserting a suitable lever +under one end, applying pressure and running a hot soldering iron up and down +the rows of pins. When one end is substantially further out than the other, +shift your lever to the other end and rock the chip out. + +ii. Desoldering Large IC's (40 pins or more) +-------------------------------------------- +This is not a task I relish, though I have had to do it a few times. I +strongly recommend the use of an IC desoldering tool. If this is unavailable, +then to help you rock the chip out (by the method described above), you should +"wet" the joints with a plentiful amount of fresh solder. + +iii. Desoldering Surface-Mounting Resistors and Capacitors +---------------------------------------------------------- +Unfortunately, one really needs to apply heat to both ends of these components +simultaneously to extract them easily. However, you can try using a +solder-sniffer to remove most of the solder, then heat up the entire component +and flick it off the board while the solder is still liquid. Make absolutely +sure you have the correct value of replacement component; SM resistors and +capacitors are often unmarked. + +iv. Desoldering 160-pin Surface Mount IC's +------------------------------------------ +Don't. It's impossible without a 160-arm soldering robot. If your motherboard +has a chip like this which is damaged, replace the motherboard; it will +probably be cheaper than trying to import a proprietary ULA from Taiwan or +Japan. Not to mention the hours you will waste soldering all those .025" pitch +pins, and the YEARS you will waste getting rid of the solder bridges. + (Note : For those who do not believe 160-pin IC's exist, please refer +to the Acer 16MHz 80286 motherboard, component U16. This is an M1207-16, a +160-pin surface-mounting ULA). + +v. Old PCB's +------------ +Printed circuit boards which have been in service for a while are MUCH more +susceptible to heat damage (when soldering and desoldering components) than +more recent boards.

These will +all become insignificant as Martin Marietta's new optical storage system +works at a terabyte per square centimeter capacity, in half the current +access time. + +OAK RIDGE, Tennessee -- Researchers at Oak Ridge National Laboratory +(ORNL), have invented a new optical storage technology capable of turning +a single molecule on an optical disc into a storage point. + ORNL, part of the Department of Energy and one of the largest +government research laboratories, is operated by Martin Marietta Energy +Systems. The department has transferred the rights to Martin Marietta, +which is now in the process of patenting and licensing the technology. +Energy Systems has started to solicit interested companies for possible +licensing agreements. + The most common methods for writing on optical discs use lasers +to burn pits or micron-sized holes or change the polarity of individual +data points in substrate sandwiched between two layers of polycarbonate. +The hardware then "reads" the change in the position of the reflected +laser's beam. The new system uses a laser or radiation beam similar to +current systems. But the unique featurea of ORNL's technology is in its +ability to go to the molecular level. + A VIDEO COMPUTING reporter talked with Mr. Guven Yalcintas +(pronounced Yal*sin*tosh), Martin Marietta's licensing director. + +V.C.: Currently we use lasers to burn pits or blisters into substrate. +What are you doing that is different? + +Mr. Yalcintas: We will license this technology to one of the companies, +an American company. We would like to protect the patentable ideas. Our +discussion will take place within that limit. In today's technology, +optical disk technology, the lasers are simply burning a hole. Well, you +can do that in this technology, too. What is new is we can write to the +media without burning the hole. We can make changes in the molecular +level. + +V.C.: Are you referring to changes in the polarity? + +Mr. Yalcintas: Yes indeed. You can change the polarity of the molecule +or you can identify that molecule as plus or minus, zeroes or ones +becoming information. + +V.C.: How do you read back the information? + +Mr. Yalcintas: Whatever source we use to change that information at the +molecular level is the same source that receives it back. + +V.C.: We currently use lasers to do that. Are you using a laser? + +Mr. Yalcintas: Yes. In fact, the laser we use has much lower power that +modifies the molecule. + +V.C.: Is this technology erasable? + +Mr. Yalcintas: This is WORM technology. You sensitize the substrate and +place the information covered with the plastic coating and the +information is going to stay there. + +V.C.: Has anyone talked about the possibility of making it erasable? + +Mr. Yalcintas: No. Let me go one step back. ORNL is a government +laboratory. It is operated by Martin Marietta for the Department of +Energy. What goes on over here every day with 5,000 plus scientists is +basic research. The research this group of scientists is working on is +a project to identify a trace amount of organic compounds in order to be +able to develop a sensor, a detecting system for minute amounts of +organic compounds. We have developed very nice operating radiation +detectors. While they were working on that research, they figured out +that they could leave information on a substrate with a laser. The +research was not directed at optical discs to store information as +WORM or erasable. One day, other research may find some easy way to +deal with that. Right now it's not the topic. Right now we are +finding out every day that WORM technology is in great demand. The +IRS wants WORM technology, the Navy wants WORM technology. The nuclear +regulatory commission wants to check data on reactors. It doesn't want +that data to be changed. For one reason, there is no funding for that, +and second, we don't believe there is any reason to erase. With this +volume of storage you don't need to erase, you just keep on storing. + +V.C.: How much data can you store? + +Mr. Yalcintas: Roughly, the size of the molecule is 10 -6E (0.000001) +centimeters, in one square centimeter you then have 10 12E molecules. +If each molecule is a potential storage spot for the data, then you +have 10 12E bytes in one square centimeter (1,000,000,000,000... one +trillion bytes per centimeter!). If you pick up a disc with 500 million +storage spots (present day CD-ROM), in the same size storage disc you are +going to have probably 500 million times one million storage spots. +That's why people are really fascinated. + +V.C.: I take it that the technology is at a fundamental level of +research. Have you done a "blackbox" yet? + +Mr. Yalcintas: No, and we are probably not going to. This office +receives 15 to 20 inventions per month. We analyze them and try to +license them. If there is a stumbling block with industry, we can go +out one more step to develop. We have maturation funding we can use +for further study, but for this project I don't believe it will be +necessary. When we show the data, people are fascinated. + +V.C.: Have you licensed the technology yet? + +Mr. Yalcintas: We have been talking to over 40 companies, 15 of which +requested non-disclosure information. Four of them have already signed, +and we have released full information to them. + +V.C.: What are other advantages of your new technology? + +Mr. Yalcintas: You can specify what part of the information can be +accessed for security purposes. It can be made secure, so the +military will be delighted. You can identify an access frequency for +someone and he can't read the rest of the disc. Also, much more +information can be entered at current optical disc speeds. The speed +for current optical discs is identified at somewhere near 1800 to 1900 +rpm. I have heard of some to 3000 rpm. Winchesters are somewhere near +3600 rpm. This is just a concept, it has not been tried, but we have +reason to believe very strongly that you can apply two substrates instead +of one. With the same laser, or frequency, you will be receiving two +different signals from two different substrates. At the same speed at +the same spot, two sets of information will be coming to you.

Manufactured with 0.8-micron +high-speed CMOS technology, the 68040 packs 1.2 million +transistors on a single silicon die. With 900,000 extra +transistors to work with over the 300,000 transistors in a 68000 +processor, the 68040's designers added new features and boosted +performance. New features include the following: + + + +-- Optimised 68030 integer unit. While retaining object-code +compatibility with previous 68000-family processors, the IU has +been optimised to execute instructions in fewer clock cycles +(i.e., run faster). The claimed boost in performance is three +times that of a 68030. + +-- Integral FPU. The 68020 and 68030 require external FPU +coprocessor chips to handle floating-point math. The 68040, +however, has an FPU built into it, giving it the power to do +serious number crunching. The FPU's data types are compatible +with the ANSI/IEEE 754 standard for binary floating-point math, +and its instruction set is object code-compatible with Motorola's +68881/68882 FPUs. Like the IU, the 68040's on-chip FPU has been +optimised to execute frequently used instructions using fewer +clock cycles. The claimed performance boost is 10 times that of a +68882. + +-- Large caches. Processor accesses to the system bus are +minimised by storing the most recently used set of instructions +or data in on-chip, 4K-byte caches. Both caches operate +independently but can be accessed at the same time. Bus snoop +logic is used to maintain cache coherence (i.e., it ensures that +the cache's contents match those parts of memory corresponding to +the cache). The bus snooper's design is fine-tuned to support +multiprocessor systems where one or more bus masters or 68040s +might share the same section of memory. + +-- Separate memory units for instructions and data. Each memory +unit consists of a memory management unit, a cache controller, +and bus snoop logic. The MMUs use a subset of the 68030's MMU +instruction set. Both memory units function independently of each +other to improve processor throughput. + +The 68040 ships with an initial clock speed of 25MHz; higher +speeds are to be available in the future, Motorola says. The +68040 comes in a 179-pin grid-array package. With the elimination +of coprocessor function lines (now that the MMU and FPU are +consolidated onto the processor) and the addition of snoop +control lines, the 68040 is not pin-compatible with the 68030. + +Because of the 68040's software compatibility with its +predecessors, it can tap into the existing software base of 680x0 +applications. It does this not only while eliminating a component +(the FPU) from a computer's design, but also while improving +performance. In fact, the 68040 executes instructions on the +average of nearly once per clock cycle -- the same as a RISC +processor. + + +Fine-Tuned for Performance + +The 68040 was built on the firm foundation of its +predecessors. The design team used the experience garnered from +developing earlier processors to aid in optimising the throughput +of the 040. + +The 040 was designed from the ground up, Motorola engineers +said. It incorporates a high degree of parallelism using a number +of internal buses. An internal Harvard architecture gives the +processor full access to both instructions and data. Both the IU +and FPU have separate pipelines and can operate concurrently. For +example, the FPU can perform floating-point instructions +independently of the IU. Each stream (instructions or data) has +its own dedicated cache and MU that function independently of +each other. A smart bus controller assigns priorities to bus +traffic to and from the caches. + +There were several key areas where Motorola was able to +boost performance. The first was in reducing the clock cycles +needed to execute certain instructions. The next was to ensure +that the processor funnels instructions and data into itself +quickly and constantly, lest it stall while waiting on +information. The processor then gets its results back into the +system without interfering with incoming information. Finally, as +if this wasn't enough, the processor stays off the system bus to +a greater extent than is the case with other processor designs. +This lets DMA transfers and other bus masters have use of it. + + +CISC with the Speed of RISC + +The IU was optimised so that high-usage instructions execute +in fewer clock cycles, particularly branch instructions. Motorola +said it performed thousands of code traces using real-world +applications to determine which instructions were used most +often. The IU consists of 6 stages: instruction prefetch, decode, +effective address calculation, operand fetch, execution, and +writeback (i.e., the result is written to either a register or to +memory). Each stage works concurrently on the instruction +pipeline. Dual prefetch and decode units deal with the branch +instructions: One set processes the instruction taken on the +branch, and another processes the instruction not taken. In this +way, no matter what the outcome, the IU has the next instruction +decoded and ready to go without seriously disrupting the +pipeline. This complex design has a big pay-off: Motorola has +determined that the average instruction takes 1.3 clock cycles to +execute. The ability to execute an instruction once per clock +cycle is the performance edge of RISC processors -- yet the +68040's IU accomplishes the same goal while executing +complex-instruction-set computer (CISC) instructions. + +The FPU adds 11 registers to the 68040 register set: Eight +of them are 80-bit floating-point registers, and three are +status, control, and instruction address registers. The FPU has a +three-stage execution unit, and, like the IU, each stage operates +concurrently. Load and store instructions (FMOVE) can be +performed during other arithmetic operations, and a 64- by 8-bit +hardware multiplication unit speeds many calculations. However, +the FPU only implements a subset of the 68882 instructions +on-chip. The transcendental (trigonometric and exponential) +functions are emulated in software via a software trap. But +Motorola claims that even these instructions should execute 25% +to 100% faster on 25MHz 68040 than on a 33MHz 68882 FPU. + + +Boosting Throughput + +In the area of throughput, each stream is managed by a +separate memory unit that uses an MMU for logical-to-physical +address translations during bus accesses. These MMUs support +demand-paged virtual memory. Both MMUs have a four-way +set-associative address translation cache (ATC) with 4 entries +(versus 22 entries for the 68030). The ATCs reduce processor +overhead by storing the most recent address translations. When an +address translation is required, the ATC is searched, and if it +contains the address, it is used immediately. Otherwise, a +combination of high-speed hardware logic and microcode searches +the translation tables located in main memory. + +Like the PU, these MMUs implement a subset of the 68030's +MMU instruction set. Gone are the PLOAD and PMOVE instructions, +because enhanced existing instructions made them superfluous. +Also, only 2 memory page sizes are supported, 4K and 8K bytes, +whereas the 68030 MMU supported 8 page sizes ranging from 256 +bytes to 32K bytes. A design tradeoff was made here: A +performance gain was possible by supporting only the 2 most +common page sizes. In any case, this change impacts only +operating-system code, since MMU instructions aren't normally +used by applications. + +The two on-chip 4K caches improve processor throughput in 2 +ways: They keep the pipelines filled and minimise system bus +accesses. To see how this is done, you must examine the structure +of the cache. Each is a four-way set-associative cache composed +of 64 sets of four lines. A line consists of 4 longwords, or 16 +bytes. Cache lines are read or written rapidly using burst-mode +access (a type of bus transfer that moves 16 bytes in a minimum +of clock cycles). For read operations, this fills the cache +efficiently and, at the same time, loads adjacent instructions or +data into the cache that could be used in the near future. + + +Zen and the Art of Cache Maintenance + +As the cache is accessed and data modified, cache-mode bits +in the ATC determine, on a page-by-page basis, the method by +which the information is handled. That is, the ATC entry that +corresponds to the address in main memory whose contents were +copied into the cache decides how the data will be updated. The +modes are cacheable write-through, cacheable copyback, +noncacheable, and noncacheable I/O. + +In the cacheable write-through mode, an update to the data +cache forces a write to main memory. While this generates +additional bus activity, this mode is required when working with +a portion of memory that other processors share. The copyback +mode updates the cache line but without updating main memory. The +modified (or "dirty") cache line is copied back into main memory +only when absolutely necessary. "Noncacheable" indicates that the +data shouldn't be cached, which is typically the situation for +shared data structures or for locked accesses (e.g., an operand +access or a translation table entry update). Noncacheable I/O +indicates that the data can't be cached and must be read or +written in the exact order of instruction execution. This mode is +for memory-mapped I/O devices (typically a serial device) where +the information's order is crucial. + +The bus snooper is used in multiple bus master situations +where a noncaching bus master, such as a DMA controller, might +modify the memory that is mapped into the 68040's cache. The bus +snooper monitors the external bus and updates the cache as +required. + +Cache validity is handled on a line-by-line basis (i.e., a +cache miss triggers a burst-mode access that updates 16 bytes +either in the cache or main memory). The copyback mode minimises +writes to main memory, and the bus controller prioritises each +cache's external memory requests. Read requests take priority +over writes to ensure that the pipelines remain filled. + +The caches are critical to the 040's overall throughput. +They keep instructions and data moving into the processor while +satisfying the apparently contradictory role of minimising system +bus accesses. Motorola estimates that the cache hit rate is about +93 percent for instruction and data reads and about 94 percent +for data writes. + + +A Processor for the 1990's + +It is perhaps appropriate that Motorola has introduced the +68040 in the first month of the 1990s. The 040 has the power to +tackle the jobs with large amounts of information that we will be +dealing with regularly in the next ten or so years. + +Preliminary results have a 68040 weighing in at 20 million +instructions per second versus the SPARC's 18 MIPS and the +80486's 15 MIPS, all clocked at 25MHz. On floating-point +operations, the 68040 antes up 3.5 million floating-point +operations per second versus the SPARCS's 2.6 MFLOPS and the +80486's 1 MFLOPS. If these numbers are accurate, then the 68040 +already out performs one RISC processor. + +But the computer industry doesn't stand still. As we move +into the new decade, we can expect new RISC processors to once +again take the lead in performance. Still, the 68040 shows that +owners of CISC systems can have their cake and eat it, too. They +don't have to forsake their software base or settle for mediocre +performance. + + +And Motorola is already working on the 68050. + +|-THiS FiLE PASSED THR0UGH --- /\ ---.------ /\ ---*--.- FiDONET 2:200/612 --| +| . * . // \ . // \ .

If you shell out between $80 and $300, and +plug the appropriate chip into that socket, then a host of +floating point instructions is added to the assembly language +instruction set. + +The original IBM-PC, and the XT, accept the original floating +point chip, the 8087. The AT accepts a later update, the 287. +From a programming standpoint, the two chips are nearly +identical: the 287 adds the instructions FSETPM and FSTSW AX, and +ignores the instructions FENI and FDISI. There is, however, a +rather nasty design flaw in the 8087, that was corrected in the +287. + +To understand the flaw, you must understand how the 86 and 87 +work as coprocessors. Whenever the 86 sees a floating point +instruction, it communicates the instruction, and any associated +memory operands, to the 87. Then the 86 goes on to its next +instruction, operating in parallel with the 87. That's OK, so +long as the following instructions don't do one of the following: + + 1. Execute another floating point instruction; or + + 2. Try to read the results of the still-executing floating + point instruction. + +If they do, then you must provide an instruction called WAIT (or +synonymously FWAIT), which halts the 86 until the 87 is finished. +For almost all floating point instructions, it should not be +necessary to provide an explicit FWAIT; the 86 ought to know that +it should wait. For the 8087, it IS necessary to give an +explicit FWAIT before each floating point instruction: that is +the flaw. + +Because of the flaw, all assemblers supporting the 8087 will +silently insert an FWAIT code (hex 9B) before all 87 +instructions, except those few (the FN instructions other than +FNOP) not requiring the FWAIT. + +* Microsoft recognizes the new 287 instructions, if and only if + it sees the .287 directive. In general, don't attempt to police + your instruction usage-- if you use an instruction available on a + limited number of processors, I trust that you are programming + for one of those processors. + +In summary, if your program will be running only on machines with +a 287, you can give ".287" directive. Your programs will be +significantly shorter than if they were assembled by Microsoft. +If you want your programs to run on all machines containing a +floating point chip, you should refrain from specifying .287. + +WARNING: The most common mistake 87 programmers make is to try to +read the results of an 87 operation in 86 memory, before the +results are ready. At least on my AT, the system often crashes +when you do this! If your program runs correctly when single +stepped, but crashes when set loose, then chances are you need an +extra explicit FWAIT somewhere. + + +Emulating the 8087 by Software + +There is a software package provided with many compilers +(Borland's Turbo C and most Microsoft compilers, for example) +that emulates the 8087 instruction set. The emulator is very +cleverly implemented so that the programmer need not know whether +a floating point chip will be available, or whether emulation +will be necessary. This is done by having the linker replace all +floating point machine instructions with INT calls to certain +interrupts, dedicated to emulation. The interrupt handlers +interpret the operands to the instructions, and emulate the 8087. + +The Floating Point Stack + +The 87 has its own register set, of 8 floating point numbers +occupying 10 bytes each, plus 14 bytes of status and control +information. Many of the 87's instructions cause the numbers to +act like a stack, much like a Hewlett-Packard calculator. For +this reason, the numbers are called the floating point stack. + +The standard name for the top element of the floating point stack +is either ST or ST(0); the others are named ST(1) through ST(7). +Thus, for example, the instruction to add stack element number 3 +into the top stack element is usually coded FADD ST,ST(3). + + +Floating Point Initializations + +In general, you use the 87 by loading numbers from 86 memory to +the 87 stack (using FLD instructions), calculating on the 87 +stack, and storing the results back to 86 memory (using FST and +FSTP instructions). There are seven constant numbers built into +the 87 instruction set: zero, one, Pi, and four logarithmic +conversion constants. These can be loaded using the FLD0, FLD1, +FLDPI, FLDL2T, FLDL2E, FLDLG2, and FLDLN2 instructions. All +other constants must be declared in, then loaded from, 86 memory. +Integer constant words and doublewords can be loaded via FILD. +Non-integer constant doubleword, quadwords, and ten-byte numbers +can be loaded via FLD. + + +Floating Point Operand Types + +The list of floating point instructions contains a variety of +operand types. Here is a brief explanation of those types: + +0 stands for the top element of the floating point stack. + A synonym for 0 is ST or ST(0). + +i stands for element number i of the floating point stack. + i can range from 0 through 7. A synonym for i is ST(i). + +mem10r is a 10-byte memory quantity (typically declared with a + DT directive) containing a full precision floating point + number. Intel recommends that you NOT store your numbers + in full precision; that you use the following double + precision format instead. Full precision numbers are + intended for storage of intermediate results (on the + stack); they exist to insure maximum accuracy for + calculations on double precision numbers, which is the + official external format of 87 numbers. + +mem8r is an 8-byte memory quantity (typically declared with a + DQ directive) containing a double precision floating + point number. This is the best format for floating + point numbers on the 87. The 87 takes the same amount + of time on double precision calculations as it does on + single precision. The only extra time is the memory + access of 4 more bytes; negligible in comparison to the + calculation time. + +mem4r is a 4-byte quantity (typically defined with a DD + directive) containing a single precision floating point + number. + +mem10d is a 10-byte quantity (also defined via DT) containing a + special Binary Coded Decimal format recognized by the + FBLD and FBSTP instructions. This format is useful for + input and output of floating point numbers. + +mem4i is a 4-byte quantity representing a signed integer in + two's-complement notation. + +mem2i is a 2-byte quantity representing a signed integer in + two's-complement notation. + +mem14 and mem94 are 14- and 94-byte buffers containing the 87 + machine state. + +The 87 Instruction Set + +Following is the 87 instruction set. The "w" in the opcode field +is the FWAIT opcode, hex 9B, which is suppressed if .287 is +selected. Again, "0", "1", and "i" stand for the associated +floating point stack registers, not constant numbers! Constant +numbers in the descriptions are given with decimal points: 0.0, +1.0, 2.0, 10.0. + + + Opcode Instruction Description + + w D9 F0 F2XM1 0 := (2.0 ** 0) - 1.0 + w DB F1 F4X4 IIT only: 4 by 4 matrix multiply + w D9 E1 FABS 0 := |0| + w DE C1 FADD 1 := 1 + 0, pop + w D8 C0+i FADD i 0 := i + 0 + w DC C0+i FADD i,0 i := i + 0 + w D8 C0+i FADD 0,i 0 := i + 0 + w D8 /0 FADD mem4r 0 := 0 + mem4r + w DC /0 FADD mem8r 0 := 0 + mem8r + w DE C0+i FADDP i,0 i := i + 0, pop + w DB E8 FBANK 0 IIT only: set bank pointer to default + w DB EB FBANK 1 IIT only: set bank pointer to bank 1 + w DB EA FBANK 2 IIT only: set bank pointer to bank 2 + w DF /4 FBLD mem10d push, 0 := mem10d + w DF /6 FBSTP mem10d mem10d := 0, pop + w D9 E0 FCHS 0 := -0 +9B DB E2 FCLEX clear exceptions + w D8 D1 FCOM compare 0 -

I am not going to explain every facet about 8- +bit computers because such a project could easily fill several +reference volumes and would require the authorship of a true +professional. I am simply going to describe my own little creation: +the preparation leading to its design and construction, the actual +processes of designing and building my computer, the long process of +finding and correcting my initial hardware problems ("bugs") and my +current, on-going exploration of the computer's capabilities from the +programming side of things. + + I first started researching the low level intricacies of 8-bit +computers about three years ago by reading Steve Ciarcia's monthly +column in BYTE magazine called "The Circuit Cellar." (I had first seen +this column as early as 1985 when I glanced through old issues of Byte +out of curiosity. Unfortunately, Steve no longer writes for Byte +magazine due to what are, in my opinion, questionable attitudes of the +management. But, lucky for his readers, Steve founded an excellent +magazine along with fellow electrical engineers devoted to hardware +"hacking" called Circuit Cellar INK. In addition to this, beginners +like myself and industry pro's can communicate with each other by +calling the CCI BBS which will be mentioned later in more detail.) In +this monthly column, Steve would present working projects along with +schematics and thorough explanations (schematic diagrams are the +detailed plans or blue-prints for an electronic circuit). These +projects included 8-bit multi-purpose control computers called micro- +controllers, a "smart" printer spooler, a logic IC (Integrated Circuit) +tester and many other interesting topics. His last three articles even +detailed a multi-processing super computer! I never built any of these +projects, but each month they taught me more and more about computer +design and gave me ideas for my own projects. + + At around the same time, I purchased a book dealing with the +Motorola 6800 microprocessor family which explained, in great detail, +the workings of 8-bit microprocessor systems. I also sent letters to +semiconductor companies such as Motorola, Rockwell and Texas +Instruments asking for information on their microprocessor, memory and +peripheral products. These companies were wonderful with the myriad of +free reference manuals that they sent me. Over a one year period of +time, I probably mailed more than 20 letters, mostly to Motorola and a +good deal to Texas Instruments, and in reply received at least 2 +bookshelves worth of valuable information in the form of their product +fliers, reference manuals and application notes (application notes are +usually sample designs incorporating a certain product for a specific +task). These companies were so obliging because the more engineers +that use their semiconductor products, the more chips they sell and the +more money they make. Nevertheless, all of this free information +supplied me with weeks worth of reading material from which I learned a +great deal. + + About a year later, I decided to design a robot based on an +article that I found in a 1986 issue of Byte. I carefully drew the +schematic diagrams for my simple circuit by hand on three sheets of +graph paper. The microprocessor that I chose for the robot was the +6808 which I had learned about from that book. Anyway, this was my +first attempt and to say "things got messed up" is an understatement. +I ordered parts, some expensive pieces of equipment to "burn" EPROM +chips (more on this later) and realized that I didn't know how to +begin. Worse yet, the science fair was about a month away. The +details are very cloudy in my head for some reason, probably because I +had no idea about what I was doing. The project was scrapped and I +think I continued to read more about electronics. + + The year after (two years ago) I decided to go ahead and build a +normal computer board, no wheels and no robot. I was able to get my +parents to buy me an expensive schematic drawing program called Schema +for my IBM clone computer to enable me to draw better diagrams. I +designed the computer around the 6808 microprocessor (MPU) again and +ordered some parts. But wouldn't ya know it...my social life got in +the way when I joined my school's production of the musical Cabaret. I +didn't start building the project till February 1st and with the +science fair a month away things went hay wire. I cut corners to build +it quickly and made a mess for the second year in a row. Thinking back +on that project, the design was a pretty good one with only a few +flaws. Had I given myself enough time I might have gotten it to work, +but who knows. + + Okay. I had enough. This was crazy. I made up my mind to build +a computer, and really build one this time. Summer vacation was over +and school had started. (We're back in September of 1989 in case you +lost track of my excellent time-keeping!) I went back to my computer +and spent some time with Schema. What a terrific program: expensive +but definitely worth ever penny to an electrical engineer. I came up +with a straight forward design for an 8-bit computer. It was again +built around the 1 MHz 6808 MPU and was to have an expansion bus +capable of addressing 32K of off-board input/output or memory, 2K or +RAM, 8K of EPROM, an LCD, a serial port capable of operation up to +19.2K baud, 8 LEDs, 4 push buttons and an 8 position DIP switch. + + Now let me do some explaining in case some of the above terms +aren't too clear to you. The 6808 that I used has an operating or +clock frequency of 1 megahertz (MHz). All computers have a certain +clock frequency which dictates how fast instructions are fetched from +memory and executed. Everything that the MPU does is synchronized by a +constant pulse train called the clock. A 1 megahertz clock speed means +that the MPU receives 1 million clock cycles per second (mega meaning +million and hertz meaning a cycle of repetition. You have probably +seen clock speeds of 10, 12, 16, 20 MHz and higher in computer +catalogs. Yes, a 30 MHz 80386 MPU receives 30 million clock pulses per +second!). Each instruction that the MPU performs is broken down into +parts and each part is executed in one clock cycle. Different +instructions have different execution times. On the 6808, the average +instruction execution time is about 4 or 5 clock cycles, ranging from 2 +cycles all the way up to 12 cycles. The faster the clock frequency, +the faster an MPU can execute instructions. Why didn't I use a 20 MHz +clock frequency? Well first of all, the highest possible operating +frequency of the 6800 family is 2 MHz. Second, the faster your MPU +operates, the more expensive and harder to build your computer gets. +At 20 MHz, you need very fast memory which ain't cheap, and you have to +be careful about other technical problems arising from radio +interference in the computer's signal lines. + + The 2K of RAM means 2 kilobytes of Random Access Memory. Thinking +back on things, I should have designed 8K of RAM...oh well. Random +Access Memory is the term given to memory that can be written to and +read from. RAM is known as volatile memory because it cannot retain +its information when power is removed from the chip. Here's something +that most people don't realize about memory quantities: the 2 kilobyte +number is a round number. The RAM chip actually has 2,048 bytes of RAM +but 2,000 is selected because it is easier to keep track of. If you're +wondering why the RAM chip is made to hold 2,048 bytes (2,048 isn't +exactly a round number), it's because computers operate on the binary, +or base 2, number system at their lowest level. All numbers in +computers are powers of 2. This is because a signal wire can either be +ON or OFF. So you have two possible numbers: 1 and 0. 2,048 is 2 +raised to the 11th power. This means that 11 address signal lines +(numbers) are needed to access all of the 2K of RAM. + + The 8K of EPROM means 8 kilobytes of Erasable Programmable Read +Only Memory. This memory is non-volatile, meaning that it retains its +information even while the power is off. Under normal operation, this +memory cannot be written to, so it is called Read Only Memory. But as +the name implies, under certain conditions the chip can be programmed +and also erased. A special device known as an EPROM programmer is +needed to "burn" the information into the chip with high voltage +electrical pulses. Another device known as an EPROM eraser is needed +to erase the information in the chip before it can be re-programmed. +This erasure process is accomplished by a high powered ultra-violet +light source. Now here's the question: why use an EPROM if you have +RAM? Well, the MPU by itself is a dumb piece of silicon wafer. +Without a program it won't do a thing so you must always have some +program immediately available for it when the computer is powered on. +The EPROM retains its data almost indefinitely, so even after power has +been turned off, it can supply the MPU with instructions as soon as the +computer is turned on. Okay great, but why do you have to make it +erasable? Once you have a perfect program developed, you don't have to +make an erasable PROM chip, but during the initial stages of +development, you must be able to correct your mistakes. If the EPROM +was not erasable, an engineer would waste dozens or even hundreds of +PROM chips before he got his program or design correct. And believe +me, no matter how perfect you think your program is the first time, +it's bound to be buggy. As you gain experience, the number of bugs of +course decreases, but they are always popping up when you least expect +it. + + The LCD is an acronym for Liquid Crystal Display. You've seen +them lots of times on calculators, watches and maybe some machines. +They can be used to display letters, numbers and graphics. The one +that I used is a 16 character display. They're not cheap though. +Buying them from retailers can set you back about $30 for the one I +used and up to $80 for a 40 character 2 line display. The best place +to buy them is from odd-lot clearing houses who buy over-stocked items +from manufacturers and sell them at great prices. I got three of them +for $30, a pretty good deal. + + The serial port is actually composed of two chips, a connector and +some assorted electronic components. The first chip is known as either +a UART (Universal Asynchronus Receiver/Transmitter) or an ACIA +(Asynchronus Communications Interface Adapter). I prefer UART because +it has only two syllables! This chip is the heart of the serial port. +It receives data from the MPU and converts it into a serial format and +then sends it to the second chip. In reverse, it takes serial data +from the other chip and converts it into 8-bit bytes for use by the +MPU. I used the Rockwell 6551 which is a very easy to use but complete +chip. Many engineers had recommended it to me. Motorola makes the +6850 which is also a UART, but I don't like it. It requires an +external clock source and is not as flexible. Heck, they made a great +MPU, so who am I to complain!?! The second chip is known as a level +converter. Standard logic levels are from 0 to +5 volts. This is +known as TTL logic (TTL means Transistor-Transistor Logic. They are +the low level basic logic circuits from which all other circuits are +built). But the RS-232 serial communications standard uses -12 to +12 +volt logic levels. Somehow, the computer industry got stuck with this +"great" idea, so we all have to design around it. The level converter +simply converts the RS-232 signals to TTL logic signals and vice-versa. +The chip I used is the MAX232 which is a great product from Maxim +Semiconductor. Unlike the standard chips used for signal conversion, +the 1488 and 1489 which require external +12 and -12 voltage sources, +the MAX232 converts +5V to +10V and -10V without any external hardware. +This minimizes circuit complexity, but increases the cost a little. + + If you've forgotten by now, I am explaining all of the parts of my +computer design! Last but certainly not least is some input/output +(I/O) circuitry that I incorporated into my design to allow status +signaling to the user through 8 LEDs and user input through a keyboard +consisting of 4 buttons and 8 switches. By the way, LED is an acronym +for Light Emitting Diode. These guys are available in several colors +and they do what their name implies: light up! All of this +miscellaneous I/O hardware is tied together for easy communication with +the MPU by the 6821 PIA. This is another Motorola product designed to +complement its 6800 family of MPUs. PIA stands for Peripheral +Interface Adapter. It has 2 8 bit I/O ports and 4 controllable signal +lines. I connected the 8 LEDs to one port, the DIP switch to the other +and the four buttons to the signal lines. Once I figured out how to +work it, the PIA performed very nicely and allowed very flexible +control of my I/O devices. + + I now take you back to the story of building the beast. We were +up to the point where I designed the computer with Schema. Okay. +During the design process, I communicated with engineers on the CCI BBS +and asked little questions here and there. They offered much help and +I soon had three nice looking pages of schematics printed out. I was +ready to build the computer, so I ordered all of the parts from mail- +order houses in silicon valley. The technique that I used is called +wire wrapping. There are two basic methods for prototyping circuits +(prototyping being the first time you are building the circuit) along +with some others: soldering and wire wrapping. Some people like +soldering. Steve Ciarcia solders all of his projects, but as someone +said on the CCI BBS, Steve was destined to be a brain surgeon. The +underside of his boards really look like art. Most of us are not so +talented and soldering can become a great mess. Melting through +insulation, twisting, turning, burning! Eech. For my previous project +(the one that I built, but didn't work) I had called the CCI BBS and +asked about prototyping methods. The general consensus was to wire +wrap. So, I bought some tools and went ahead with it. The wire +wrapping part of my previous project was certainly a success. The +process is very easy to learn. + + This year, I ordered some more wire and assorted materials +necessary to build the project. It was a hefty bill, but I paid some +and my parents paid some. I started building it, I think, in October +or November. In any case, I finished in a few weeks and was ready for +the initial test by December. Everything looked great, but I was +scared as hell to try the thing out. I soon got up the nerve to +program an EPROM with a simple program and plugged it into its socket. +I turned the power on with a rapid heart beat and relaxed. The damn +thing didn't even cough! It just sat there with the power on. No +smoking, no explosions, no LEDs going on, no words on the LCD. I was +disappointed, but did I really expect it to work? No, I really looked +at it as something that I couldn't possibly get to work. I mean...me +build a computer? Come on, a computer is a computer, not some lego set +or something like that. I gave it a few more tries and still nothing +happened. I checked my design and everything seemed okay. I checked +the wiring and everything seemed okay. + + Okay. I decided to check the power rails. I took out my multi- +meter which I bought at Radio Shack on sale for $9.95. A multi-meter +is an instrument that can measure several electrical characteristics of +wires. The most basic multi-meter (what I had) can measure voltage and +resistance. I selected voltage mode and put the probes to my power +rails. Hey! I found something. The voltage read almost 0 which meant +that either my power supply was not functioning or there was a short. +I checked the power supply and it was fine, so there must be a short... +but where? I called the CCI BBS once again and asked for some help. +About two weeks later, I found the short with a technique that an +engineer had explained to me. Okay. I'm ready. Again I plugged in +the EPROM and again nothing happened. After a few more desperate +tries, I gave up. It was now the beginning of January. I decided to +stop work until February. + + About two weeks later, I logged onto the CCI BBS as I always did +weekly and found a message waiting for me. It was from an engineer in +silicon valley who had started working with 8-bit MPUs when he too was +a sophomore in high school. I was then a Junior, but that's beside the +point. He gave me encouragement and some hints on how to find my +short. I wrote back thanking him for the encouragement but telling him +that I found my short and that the computer still didn't work. I was +confident of my design because of those I had seen in Steve's column +and in the new magazine Circuit Cellar INK. He soon replied with some +trouble-shooting techniques. The first one was a simple test to +determine if the MPU was actually executing instructions. It consisted +of a single jump command that keep jumping back to itself. I tried it +and it worked. This was amazing. For the first time, I actually had +some assurance that my design had some life in it. Knowing this, I +decided to scrap the fancy demo program I wrote and go for a simple LED +flasher. I wrote the program and burned it into an EPROM. But it +didn't work. This was very disappointing, but I didn't give up this +time, because the first test had worked. + + After a few hours of playing around, I found the problem! Three +address lines were wired backwards to the address decoder chip. Time +for some background: most 8 bit microprocessors can address 64 +kilobytes. This actually equals 65,536 bytes because there are 16 +address lines. Since the computer does not consist of one big 64K RAM +or EPROM chip but rather several smaller (smaller in terms of the +number of bytes they occupy in the address space) peripherals, this +large address space must be divided. A common denominator is 8 8K +chunks of memory. The top three address lines (A15 through A13) are +connected to an address decoder which determines which memory block is +currently active according to these three address lines. Because we're +working with the binary number system, three binary digits can +represent 8 combinations. The decoder chip, in this case a 74LS138 +decoder chip, activates one of eight enable signals depending on the +content of the three address signals that it receives. Now, how does +this represent a problem to me if the three lines are wired backwards? +Well let's take the example that I had. My LED flasher program needed +to address the 6821 PIA so that it could turn the LEDs on and off. +This PIA is connected to the second 8K memory block enable line coming +from the 74LS138 decoder. To select this second memory block, the MPU +had to place the digits 001 on the lines A15-A13. But if the three +address lines were wired backwards, the decoder would see 100 instead +of 001 and would select the wrong memory chunk. I discovered this +problem by monitoring the decoder's memory enable lines with a logic +probe. The logic probe simply tells me whether the signal line is high +(1) or low (0). For some strange reason, the second memory block was +never being accessed, but the fourth was. After some thought, I +realized that the binary number representation for 4 was the exact +opposite for that of 2. I ran upstairs to get my reference book and +sure enough, the decoder was getting the signals in reverse order. + + I went back upstairs and fixed the problem. One very big +advantage of wire wrapping is that mistakes can easily be fixed. All I +did was unwrap the wire from the three signal lines and I rewrapped +them. It took about 5 minutes to do. I plugged the EPROM back into +its socket and poof! My LEDs were flashing! True, my complicated +computer didn't look like much more than a christmas tree, but I knew +that it was working. The LEDs were not flashing on their own: the MPU +was telling them to flash. Now this was a victory! + + Once I got to this point, things started falling into place. +Within a week and a half I got everything working perfectly. Sure, +there were troubles but I got them resolved. The only modification I +still have to make is an enable circuit for my expansion bus. I forgot +to design one in and because of that the bus cannot be used. But +that's okay for now because I am not yet building peripheral cards for +my computer. I am now working on a terminal program that will enable +me to download programs to the computer's RAM from my communications +program on my IBM clone. It should be working within a week. + + Some miscellaneous problems that I encountered and fixed include: +two signals on the serial port were wired backwards, one wire on my LCD +was broken, the expansion bus mystery mentioned above, some pull-down +resistors that should have originally been pull-up resistors and +connecting the LEDs to the other I/O port instead of the one it was +originally connected to. It was like unravelling a mystery plot, +almost every day after I got the LEDs flashing, something new fell into +place and started working. From here on in, its just a matter of +software. The hardware is all done (whew!) and now I just have to deal +with it from the programmer's point of view. + + The programming isn't bad, but now and then you get a little bug +that drives you crazy until its found and eliminated. The entire +project was and continues to be a great learning experience and usually +alot of fun. Maybe one day, you'll see my name on a super computer?! +Who knows. I got the baby purring and from here the sky's the limit. +My next project is going to be a faster computer with a monitor, full +keyboard and disk drives. I probably won't get it right on the first +power up, but now that I know my computer works, every other problem +will be a minor inconvenience! + +X-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-X + + Another file downloaded from: NIRVANAnet(tm) + + & the Temple of the Screaming Electron Jeff Hunter 510-935-5845 + Rat Head Ratsnatcher 510-524-3649 + Burn This Flag Zardoz 408-363-9766 + realitycheck Poindexter Fortran 415-567-7043 + Lies Unlimited Mick Freen 415-583-4102 + + Specializing in conversations, obscure information, high explosives, + arcane knowledge, political extremism, diversive sexuality, + insane speculation, and wild rumours.

About 58ns after _AS goes low, _RAS +will also go low. Depending on what kind of access it is (WORD BYTE READ +WRITE) one or two _CAS lines will go low either 94ns (READ) or >100ns (WRITE) +after _AS low. Remember that on the 68000, _UDS/_LDS go low at the same time +as _AS for a READ, but are delayed for a WRITE. That is why they go thru the 2 +OR gates (U11). This ensures that _CASxx will fall at the right time. +When _AS goes high at the end of the cycle, _CASxx goes high first, then _RAS. + +REFRSH MODE +The DRAM memory is being used in _CAS before _RAS refresh mode. This means +that if _CAS is brought LOW about 20ns before _RAS, the DRAM automaticly +selects what row to refresh. Only 64k x 4, 256k x 4 and 1meg x 1/4 support +this feature. Otherwise, there would need to be counters and stuff added, +maybe 5 more chips. When the CPU accesses CHIP ram ($0 to $1FFFFF), Y0 of U1 +goes LOW. This is the signal that says 'Time to refresh, cuz we ain't gonna be +needed on this cycle'. All _CASxx lines will come low 72ns after _AS LOW, +followed by _RAS LOW 100ns after _AS LOW. So the time diff between _CAS and +_RAS is about 28ns, within the 20ns min parameter. The chip is kept refreshed +untill the cycle ends. + +CONSTRUCTION: +This design uses D0-D15, A1-A23, R/W, _AS, _UDS and _LDS. All these signals +can be found at the expansion port of the 500, or CPU/Zorro slots on a 2000. +For 500 owners ,this board could also be placed under the 68000 itself, +saving your expansion port for better things. As long as you provide a good +power path, there should be no problems. My proto-type board with 2megs used +around 300ma while running Memory_Doctor, and 169ma just sitting there, no +programs running. It uses ALOT more than my GrandSlam (90ma) for refreshing, +but I'm not using custom chips and they are. For a 500 supply, 8megs might be +more than it can handle, so consider buying a 150-200w switching supply (any +AT type will do since they cost half as much as a '500 specific' supply). + +SIMM sockets cost ALOT of bucks, so you may want to spend a $1 more and buy +SIPP ram (with the pins). Those can fit into normal IC sockets (Just to give +you an idea, 8megs of SIPP sockets cost $21, while 12 20pin sockets cost +$2.50). The SIPPs will tend to sit in at an angle, so fashion some type of +brace for them. If you use SIPP ram, the board won't fit inside a 500, but +low-profile SIMM sockets just might. + +Get the exact same parts that I have in the parts list. Don't sub an HC for an +LS. All types have been chosen for their propagation times. Best place to get +the parts is Active Components. They are cheap, and always have good stock. I +have heard of people being charged upto $2 a chip at some other places (Radio +Shack, WES). Board layout isn't critical, but use some common sense, try and +keep data and address lines together, and so forth. Wire wrapping is OK. + + +ADDING RAM: +You can use 1meg by 8 (or 9, some place charge MORE for the 8bit sipp!), or +256k x 8/9 sipps. To use the 256k, they must have only 2 chips on them (3 if +it is a 9bit simm). Why? The ones with 8 or 9 chips use 256k x 1 type DRAM +chips. Those are fine in other ram expanders but not here. They DON'T support +_CAS before _RAS refresh. The 256k x 4 do, so that's what type you need. + ___________________________ ___________________________ + | || || || || || || || || | |-------- -------- ----| + | || || || || || || || || | |-------- -------- ----| + uuuuuuuuuuuuuuuuuuuuuuuuuuu uuuuuuuuuuuuuuuuuuuuuuuuuuu + These won't work!

Recently, however, several manufacturers have +creatively combined relatively mature techniques of data transmission with +newer technology and have introduced 9600 bps modems. + +Unfortunately, a widely accepted standard for full duplex 9600 bps +transmission as defined by the International Consultative Committee for +Telegraphy and Telephony (CCITT) does not yet exist (the CCITT is currently +considering proposals for a new 9600 bps dial-up standard). This means that +today's 9600 bps modems do not offer cross-manufacturer compatibility. The +CCITT HAS endorsed a half duplex and a full duplex 9600 bps standard, but to +date implementations of these relatively flexible standards have been +proprietary, i.e., even the "standardized" modems from different manufacturers +are not compatible. + +All this means that modem users who want to enjoy the dream speed of 9600 bps +must weigh the pros and cons of each 9600 bps technique before committing to a +particular 9600 bps design. This paper was written in an effort to provide +typical modem users with enough technical information and insight that they +will be able to consider the new 9600 bps modems from the position of an +educated consumer and not have to rely on information gleaned from sales +brochures and advertisements. It should be noted that the author, Wes Cowell, +is an employee of USRobotics. + + THE ROAD TO 9600 + +High speed data communications via the dial-up phone network is limited by the +available phone line bandwidth and by random channel impairments. Just as the +diameter of a pipe limits its liquid flow capacity, so does the telephone +channel bandwidth limit its data flow capacity. + +The roughly 3000-Hz available in the telephone bandwidth poses few problems +for 300 bps modems, which only use about one fifth of the bandwidth. A full +duplex 1200 bps modem requires about half the available bandwidth, +transmitting simultaneously in both directions at 600 baud and using phase +modulation to signal two data bits per baud. "Baud rate" is actually a +measure of signals per second. Because each signal can represent more than +one bit, the baud rate and bps rate of a modem are not necessarilly the same. +In the case of 1200 bps modems, their baud rate is actually 600 (signals per +second) and each signal represents two data bits. By multiplying signals per +second with the number of bits represented by each signal one determines the +bps rate: 600 signals per second X 2 bits per signal = 1200 bps. + +In moving up to 2400 bps, modem designers decided not to use more bandwidth, +but to increase speed through a new signalling scheme known as quadrature +amplitude modulation (QAM). + +In QAM, each signal represents four data bits. Both 1200 bps and 2400 bps +modems use the same 600 baud rate, but each 1200 bps signal carries two data +bits, while each 2400 bps signal carries four data bits: +600 signals per second X 4 bits per signal = 2400 bps. + +A technique known as adaptive equalization enables 2400 bps modems to adapt to +phone line impairments call-by-call. Essentially, if the modem is experiencing +problems with a noisy line, it looks for a "sweet spot" in the bandwidth and +attempts to avoid troublesome frequencies. This technique makes 2400 bps +modems more tolerant of line noise than their 1200 bps counterparts that use +compromise equalization (a one-size-fits-all approach). + +While these advanced modulation and equalization techniques in 2400 bps modems +provide for double the data rate of 1200 bps modems, they also result in a +design at least four times more complex than 1200 bps modems. + +Which brings us to the problem of designing a 9600 bps modem. + +Jumping to 9600 from 2400 bps is several orders of magnitude more complicated +than going to 2400 from 1200 bps. Telephone network characteristics make it +highly unlikely that success will be had in extending the "data signal +alphabet" (number of bits represented by each signal) beyond four bits per +signal. + +Instead, modem designers must increase the bandwidth that is to carry the +signal, and this presents a very big problem. In fact, at speeds of 4800 bps +(1200 signals per second), the transmit and receive channels must be expanded +to the point where they actually begin to overlap. A 9600 bps "band" +requires roughly 90 percent of the available bandwidth, making it impossible +to have two-way communication without the bands interfering with each other. + +A helpful analogy to the problem might be to consider a two lane highway: +traffic must flow in both directions simultaneously, but to carry more cars +per unit of time, highway designers must either increase the number of lanes +in each direction or widen the two lanes to accommodate driver error with a +margin of safety. Unfortunately, these options are not available to modem +designers as the available bandwidth is of a fixed size. + +With these considerations and limitations in mind, let's examine three basic +ways to accomplish full duplex (two-way) 9600 bps communications: echo +cancellation, virtual full duplex (achieved by half duplex systems), and +asymmetrical frequency division. + + ECHO-CANCELLATION + +This method solves the problem of overlapping transmit and receive channels. +Each modem's receiver must try to filter out the echo of its own transmitter +and concentrate on the other modem's transmit signal. This presents a +tremendous computational problem that significantly increases the complexity +-- and cost -- of the modem. But it offers what other schemes don't: +simultaneous two-way transmission of data at 9600 bps. + +The CCITT "V.32" recommendation for 9600 bps modems includes echo- +cancellation. The transmit and receive bands overlap almost completely, each +occupying 90 percent of the available bandwidth. Measured by computations per +second and bits of resolution, a V.32 modem is roughly 64 times more complex +than a 2400 bps modem. This translates directly into added development and +production costs which means that it will be some time before V.32 modems can +compete in the high- volume modem market. + +Despite the fact that V.32 is a recognized standard, it is uneconomical and +unnecessarily complex for personal computer datacomm applications that simply +don't require simultaneous two-way 9600 bps transmission. + + HALF DUPLEX SYSTEMS + (Virtual Full Duplex) + +Half duplex solutions devote the entire bandwidth to 9600 bps in one direction +at a time, and "ping-pong" the data flow back and forth to simulate full +duplex. This is potentially the simplest scheme. Its performance is +acceptable in data transfer applications that don't involve user interaction, +i.e. file transfers. Even so, advanced error-control protocols that require +ACKnowledgments to be sent in response to received data blocks generate a high +number of "line reversals" which greatly impair overall data throughput. In +short, the benefit of higher speed is so significantly compromised by line +reversals in half duplex sessions that the net gain in data throughput may be +marginal at best. + +If users want to operate in an interactive mode, their data must be sent to +the remote computer, the data channel must be reversed, and then the data must +be echoed back. This process results in significant turn-around delays which +can be very frustrating to users. + +Half duplex modems of this kind are most often based on CCITT recommendation +V.29 for half duplex 9600 bps transmission on the dial-up network. V.29 based +data pumps used in facsimile systems are available as LSI chip sets, providing +a short-cut to modem manufacturers, particularly to companies that don't +develop their own modem technologies. But the major problem is that the V.29 +modulation scheme has been outdated by the fact that it operates in a half +duplex mode and doesn't provide good signal to noise performance. The V.32 +recommendation, which operates in a full duplex mode and employs Trellis +Coding Modulation offers greater throughput and a greater immunity to channel +impairments. + +To the best of my knowledge, modems employing V.29-based modulation include +products from Racal-Vadic, Comspec, Develcon, Gamma Technology, Microcomm, and +Electronic Vaults, Inc. (EVI). These modems, however, are NOT mutually +signal compatible -- cross-manufacturer compatibility does not exist. + +Another modem in the half duplex category, but not based on V.29 modulation, +is the Telebit Trailblazer (R), which uses a proprietary modulation method. + +Trailblazer is based on a multi-carrier technique. Conceptually, the +transmission channel is divided into many (512), independent, very narrow +channels (think of our two-lane highway and imagine it as having 512 very +narrow lanes (say, for bicycles) going in one direction and you've got a fair +idea of how Trailblazer divides the bandwidth). The main advantage is that no +receiver adaptive equalizer is needed because each channel is very narrow +compared to the overall channel bandwidth. + +Further, in the Trailblazer modulation scheme, the modulation rate in each +narrow channel can be changed somewhat independently. Trailblazer is +different from many other modems in that the decision to fall back to lower +speeds is built into the modem protocol, rather than controlled by the user's +computer port. It is claimed that in the face of channel impairments, +throughput can be adapted gracefully to channel conditions. Traditional +modulation systems would have to fall back in larger steps. But there are +three inherent MAJOR problems: + +1) The turn-around delay is very long compared to conventional modulation +techniques because data must be sent in large blocks. A typed character may +take several seconds to be echoed back to the system that sent it. As a +result, the system fails to achieve the illusion of full duplex and is not +really suited to interactive online sessions. + +2) The Trailblazer receiver cannot "track" carrier "phase jitter" (phase +jitter can be thought of in terms of "phase shift": think of how the whine of +a race car goes from higher to lower as it passes the viewer -- the frequency +of the sound is said to be "shifted" or "jittered"). Instead of cancelling +out phase jitter (which is commonly encountered on long distance calls) the +Trailblazer can only respond by lowering throughput to gain more immunity to +phase jitter. + +3) The ability to transmit at the maximum rate when subject to channel +impairment is considerably less than for conventional modems. There is one +notable exception: the multiple channel technique offers extremely good +immunity to impulse noise because the impulse energy is distributed over +narrow channels. While conventional modems can achieve similar results +through special coding or filtering techniques they rarely implement such +methods. + + ASYMMETRICAL FREQUENCY DIVISION + +When one considers the nature of most PC datacomm applications, it is realized +that most applications are interactive, involving manual (typed) data entry +from one end and data file transmission from the other end. + +Few, if any, PC users can justify using an expensive 9600 bps channel to carry +their typed characters when they realize that 300 bps translates to 360 words +per minute. Assuming one could type 100 words per minute, even a 100 bps +transmission channel would be sufficient. + +On the other hand, file transfer should take advantage of the tremendous speed +of the microprocessor. Serial ports are often set at data rates in excess of +19,000 bps. + +Considering these inherent characteristics, a communications scheme that +incorporated a high speed and a low speed channel would be best suited for +most PC datacomm applications. + +Remembering the highway analogy (higher speeds mean wider lanes), one can see +how such a method would grant modem designers a large portion of the +available bandwidth for a 9600 bps channel and still leave enough room to +accommodate a narrow 300 bps channel without any channel overlap. + +By utilizing two discreet channels, such a modem would avoid costly, complex +echo-cancellation schemes. And, because the channels carry data in both +directions simultaneously, the communications link is a true full duplex +connection. This means that data entered at one system would be almost +instantaneously echoed back -- eliminating the frustrating turn-around delay +experienced in half duplex sessions. + +USRobotics has developed just such a modem. It passes data in one direction +using the V.32 modulation technique (a very robust method that is very immune +to phone line impairments) but employs only a 300 bps channel in the opposite +direction so that the channels do not overlap and echo-cancellation is not +necessary. + +The use of the high-speed channel by the two modems is based on data demand. +In most applications, however, "channel swapping" will not be required. For +interface elegance, the modems employ a 4K buffer that allow them to perform +data rate conversion: sending and receiving speeds remain constant between the +modem and the computer -- it is only in between the modems that transmitted +and received data run at different speeds. + +For interactive sessions, users are assigned the low-speed channel while the +data sent to them (long mail messages, menus, files, etc.) in the 9600 bps +channel. + +For file transfer sessions, the data blocks that make up a file are sent in +the 9600 bps channel while the corresponding ACKnowledgments are returned in +the 300 bps channel. An asymmetric frequency division scheme is ideal for +file transfer where large data blocks (usually several hundred bytes in +length) are transmitted in the high-speed channel and the ACKs (usually only +a few bytes in length) are carried in the low-speed channel. + +If a user switches from an interactive mode to file transfer and then back to +interactive mode, the high speed channel is dynamically and automatically +assigned to the system with the greatest data demand. + + A BRIEF COMPARISON + +Three options exist for data communicators who desire to operate at 9600 bps: + +1) V.32-type modems offer a full duplex connection but do so by virtue of +echo-cancellation. This technique is so complex, and has proven so difficult +to employ, that the cost for such modems will remain prohibitively high and +their implementation a delicate task for some time to come. + +2) Half duplex modems (either V.29 or multi-carrier) offer 9600 bps but the +turn-around delay inherent in half duplex links severely compromise overall +throughput. This degradation of throughput, however, can be more than offset +by data compression techniques assuming the modems in question support +identical compression protocols and are operating on relatively "clean" phone +lines. Both half duplex methods suffer disproportionate degradation on +"noisy" lines: the V.29 modems must spend more and more time in line reversals +as detected data errors increase, and the multi-carrier modems must sacrifice +throughput to gain noise immunity. + +3) Asymmetrical Frequency Division offers 9600 bps communications in a true +full duplex implementation. By efficiently utilizing the available bandwidth, +these modems provide users with high speed file transfer capabilities and fast +response in interactive sessions. Because the transmit and receive data +channels do not overlap, expensive echo-cancelling techniques are unnecessary +making these modems economically efficient. + + IN CONCLUSION + +Until a widely recognized standard is agreed upon by the standards community, +and implemented by several manufacturers, modem buyers must weigh the benefits +and detriments of each 9600 bps scheme. + +V.32 would be best where symmetrical, full duplex, synchronous communication +is desired (for example, dial-up HDLC links between multiplexers) and where +the user can modify his software to accommodate non-"AT" command-driven +modems. + +V.29 modems would be likely solutions where absolute lowest price is required +and conformance to an international standard (in a very limited sense) is +desired. + +Multi-carrier transmission schemes are well-suited to applications that +require maximum one-way throughput and where circuit conditions are known to +be good. This transmission method is also ideally suited for circuits where +immunity to impulse noise is paramount. + +Users who most often work with one-way file transfers (PC-to-PC) or with real- +time applications may opt for an Asymmetrical Frequency Division scheme, which +is suited equally well for either application. The elegant approach to the +frequency division (avoiding overlapping bandwidths) also allows these modems +to present a very economical ratio between dollars and bps. + +Potential high-speed-modem buyers should also consider the aspects of ease-of- +use, ease-of-implementation, and downward compatibility with existing +implemented standards (the CCITT's V.22bis for 2400 bps, Bell 212A for 1200 +bps, and Bell 103 for 200 bps). + + POST SCRIPT + +Many modem users have voiced confusion and consternation about the lack of +compatibility between modem manufacturers at speeds greater than 2400 bps. + +Modem manufacturers have embraced the Bell 212A and 103 standards for 1200 and +300 bps. In these post-divestiture days, however, Bell no longer sets modem +standards in the U.S. and hence, U.S. modem manufacturers have turned to the +CCITT as a definitive source for standards. The industry-wide acceptance of +the CCITT's V.22bis standard for 2400 bps is the best example of this shift. + +The CCITT recommendations V.29 and V.32 for 9600 bps have not resulted in +compatible implementations. It is important to remember that V.29 was +originally developed as a four-wire full duplex leased-line modem and has +since been adapted by various manufacturers to encompass half duplex dial up +applications. Other problems with V.29 are that it compromises transmission +speed and is poor for interactive sessions. V.32 is proving to be +prohibitively complex and exceptionally difficult to implement (driving +development and production costs up). + +Recognizing the need for an alternative to the V.32 recommendation, the CCITT +has requested proposals from modem manufacturers. + +Presently, two proposals are being considered by the CCITT. One is the multi- +carrier scheme developed and sponsored by Telebit. The other is an +Asymmetrical Frequency Division scheme developed and sponsored by USRobotics. + +  and s \ No newline at end of file diff --git a/textfiles.com/computers/9600data.txt b/textfiles.com/computers/9600data.txt new file mode 100644 index 00000000..20d94f96 --- /dev/null +++ b/textfiles.com/computers/9600data.txt @@ -0,0 +1,647 @@ +Filename: 9600DATA.TXT +Version : 1.2b +Updated : 1/11/1991 +------------------------------------------------------------------------------- + + A Comparison of High Speed Modems + Compatibility/Features/Differences/Prices + + Including: HST, V.32, V.32bis, V.42, V.42bis + + + By Mike Ehlert, SysOp: PACIFIC COAST MICRO BBS + USR HST/V.32bis (805) 494-9386 + USR HST 14.4k (805) 497-3456 + CC Speedmodem (805) 496-7320 + FidoNet 1:206/2801 +------------------------------------------------------------------------------- + + TABLE OF CONTENTS +A High Speed Modem +Disclaimer +Standards +The CCITT +Half-Duplex Vs.

All other modems tried to be +"Hayes Compatible". This is still true with 1200 and 2400 bps modems, +but NOT when it comes to 9600 or faster modems. Hayes established a Standard +called the AT command set. Other modem manufacturers quickly adopted this +standard and the AT commands are still used today (with a few commands added). + +Well Along Came USRobotics, and designed the HST, a proprietary 9600 modem +that quickly became popular, and no one else was allowed to duplicate. +Hayes then also came out with a proprietary 9600 modem, but since it could not +talk to the HST at 9600 it never became popular in the IBM world. +Next USR improved their HST modem, making it transfer at 14400 bps without +even using data compression. +USR's HST became the standard for MS-DOS computable High Speed modems. + +Realizing that the industry needed a "non-proprietary" 9600 standard that +any manufacturer could use, the CCITT came up with the V.32 specification. +It took a several years before modem manufactures started finding ways to +implement this standard at a price competitive to HST, but a few manufactures +started producing them, including Hayes. Next the CCITT realized that better +error correction and data compression methods existed, and thus came up with +the V.42 and .V42 bis standard. They are currently finalizing the V.32bis +specification, which will also run at 14,000 Baud in full duplex. + +Now Modem Manufactures all seem to be jumping on the V.32 Bandwagon, +Even USR offers V.32/V.42 modems and allows the HAT's to be upgraded to +a "Dual-Standard" so it can be both HST and V.32/V.42 in one. +The New Hats also have V.42bis and can be upgraded to the new V.32bis DS. +The price Difference between the HST and the HST-DS is considerable though, +which is why Most BBS Sysops still buy the HST without the "DS" option. +The V.32/V.42 have become the standard in the Macintosh world, and some +MS-DOS BBS's are now running V.32/V.42 instead of supporting the HST, +and some are supporting both types, using multiple lines. + +Fax Machines have had their own standards, CCITT V.27, V.27ter, and V.29 +define the modulation scheme used for Fax, and T.30 defines a Fax Protocol. +Fax Machines nowadays can transfer Faxes at 4800 or 9600 Baud. Most Fax/Modems +can only transfer files at 2400 Baud. There is now one Fax/Modem which can +also transfer files at 9600 bps, and is far less expensive then the V.32/V.42s, +plus offer the benefits of a Fax machine. + +--------------------------------------------------------------------------- + + The CCITT + ========= + +The International Consultive Committee for Telegraph and Telephone (CCITT) +set the V.32, V.42, and V.42bis Standards in 9600 bps communications. +They have also set the standards of 1200 and 2400 bps in Europe. +Unfortunately the V.32 standard is very expensive to implement for the +modem manufactures, and the HST has already become the industry standard +in the IBM BBS world. But since any company may manufacture V.32/42 Modems +without a license or royalty, there is more price-competition going on +with these then with the HST, which currently has no true competition. + +----------------------------------------------------------------------------- + + Half Duplex Vs. Full Duplex + =========================== + +Half-Duplex is When Data is Transited in one Direction at a time. +Full-Duplex is both directions at once. 2400 baud modems are Full-Duplex. +The HST Modem uses an improved form of Half-Duplex, in which one direction is +transferring at high speed while the other direction is sending ACK/NAK signals +at a slower speed. A similar method is used on the Speedmodem. + +V.32 modems use Full duplex, which in most cases does not improve performance +when used on a BBS. There is one way to take full advantage of a Full-Duplex +Modem: By using a protocol called Bimodem to upload and Download as the same +time at 9600 bps in each direction! Unfortunately Bimodem has not become very +popular. Most BBS's and users still use one direction transfer protocols such +as Zmodem or YModem-G. + +------------------------------------------------------------------------------- + + What is MNP, HST, V.32, V.42? + ============================= + + MNP + +MNP (Microcomm Network Protocol) levels 1-4 are methods of error correction +in which the two modems connected verify the integrity of the data transmitted. +Error correction is required for several streaming protocols such as Ymodem-G +in which the protocol sends a constant stream of data and lets the modems do +the error correction. This requires a clean, noise free line as streaming +protocols will abort if line noise interferes too much. +These MNP Levels are used in almost all High Speed Modems Made today, But +Just because two modems both have MNP it does not ensure that they will both +talk to each other (at over 2400 baud). + +MNP Level 5 is for data compression. Since All BBS's have their files archived +in ZIP, LZH, GIF or some such compressed format (try to ZIP a LZH file), MNP5 +can actually increase the overhead by attempting to compress the file further. +Therefore BBS's leave MNP5 turned off, and so should the BBS callers. + +------------------------------------------------------------------------------- + + HST + +HST stands for "High Speed Technology" - a method of communicating at high +speeds which was developed by US Robotics in 1984. HST is a proprietary +method so currently only US Robotics is allowed to Make HST Compatible Modems. +The original HST modems were 9600 bps by using a 9200 bps channel in one +direction and a 450 bps "back channel" in the other to send ACK/NAK +signals for confirmation of data - a half duplex mode - often referred to +as "ping-ponging". In 1989 USR improved the HST to run at 14400 bps by further +optimizing their proprietary method. All HST's sold now include the 144k +speed as well as the original 9600 mode. Because the HST 14.4k is a raw speed, +It allows the HST to transfer pre compressed files such as ZIPs at faster +speeds then any other 9600 modem: over 1700 Characters per second. + +The HST has become the "BBS-Standard" in high-Speed Modems. More BBS's use +the HST then any other type of modem, including the V.32. + +As of January 1st 1991 all HST modems also include the V.42/V.42bis error +correction and data compression (not to be confused with V.32). + +The HST's can also be upgraded to the HST "Dual Standard" allowing it to also +be V.32bis compatible. The price is significant for this upgrade however, +and in very few cases is any speed gained. + +------------------------------------------------------------------------------- + + V.32 + +V.32 is a 9600 Baud standard that was established by the CCITT back in 1984. +V.32 is full duplex (9600 bps in both directions at once). Normally this would +be impossible, but using a technique called "echo cancellation", one modem +can filter its own tones from the phone line, enabling it to pick out the +signals from the other modem. However, echo cancellation requires that high +speed modems include built-in digital signal processor (DSP) chips, which is +the main reason V.32 and V.42 costs so much. +V.32 also includes a fall back to 4800, if line noise becomes a problem at 9600. +The V.32 standard also provides an optional error-reduction scheme, called +"trellis-coded modulation (TCM). TCM allows 9600 modems to check for +transmission errors with a redundancy bit, which results in fewer errors on +noisy lines. Most V.32's include this option, but some do not. + +------------------------------------------------------------------------------- + + V.32bis + +It was first realized in 1989 that it is feasible to push V.32 up to 14,400 +baud, the same speed as the HST now runs. This requires even better echo +cancelers and an overall improvement in receiver quality, so it will be +more costly to produce than the V.32 to produce. V.32bis has not yet officially been +finalized CCITT, but as of January 1st US Robotics has started shipping +a new version of their Dual Standard Modem which includes V.32bis in an early +but functional form. USR plans to update their DS ROMS when the CCITT actually +release the completed V.32bis specification, scheduled for mid 1991. +It's expected that other Modem manufacturers will not be able to offer the +V.32bis technology until the 4th quarter of 1991. + +------------------------------------------------------------------------------- + + V.42 + +V.42 is nothing to do with actual modem speed, but how the error correction +and data compression schemes interface. When the CCITT approved V.42 in 1988, +they decided to include two different error correction and data compression +schemes. The first one is MNP,(short for Microcom Networking Protocol). +MNP classes 2, 3, & 4 which handle error correction. Note that MNP-5 was not +included in the V.42 standard because it is only used for data compression. +MNP was made an official standard due to the large number of modems that +currently use it. The Second method is the preferred method, known as LAP-M +(Link Access Protocol-Modem). A modem with only MNP is called "V.42 Compatible" +and one with LAP-M its known as "V.42 Compliant". If a V.42 Compliant connected +to a V.42 compatible, it would first try to Handshake with LAP-M, and after it +realized that the other modem is not Compliant, it would try the MNP Method, and +they connect. + +Most V.42 modems are fully V.32 compatible, but they do NOT have to be, +according to CCITT guidelines. So when purchasing a V.42, make sure that +it is really a V.32 Modem that is also V.42 compliant or compatible. +There are now some 2400 baud modems which are also V.42bis compliant, +so since the LAP-M gives 4:1 data compression they are advertised as +"9600 throughput", which really can be misleading and confusing. + +------------------------------------------------------------------------------- + + V.42bis + +V.42bis is a new CCITT standard for data compression techniques, which was +approved in late 1989. To Support V.42bis, a modem MUST support both LAP-M and +MNP-5, unlike the Standard V.42 in which LAP-M is only an option. V.42 provides +a maximum data compression of 4:1, giving a 9600 bps modem a throughput up to +38400 bps. MNP only offers 2:1 Compression. Like MNP-5, LAP-M and V.42bis will +not be effective when transferring compressed files from BBS's, such as ZIP +files. Since V.42 is implemented in firmware, many V.42 compliant modems can +be upgraded to V.42bis with a new ROM. + +------------------------------------------------------------------------------- + + Speedmodem + +A less expensive method of 9600 bps communication can be achieved without +using the CCITTs method of "echo cancellation", so that the a digital signal +processor is not needed, making the cost much less expensive. +This method is used on the Compucom Speedmodem. The Speedmodem also uses +Dynamic Impedance Stabilization (DIS) to increase the reliability of the +telephone interfaces signal-to-noise ratio of the telephone line by increasing +the clarity and power of the signal, and automatically compensating for +impedance variations on the phone line. This reduces the probability of +line noise, allowing the Protocols to transfer files with less overhead +It also has a faster fall back rate of 7200 bps if too much line noise exists +for 9600 communications. This makes the Speedmodem stand up to worse line +noise conditions at a faster rate then V.32 can handle. +The Speedmodem is also a 9600 bps Group III Facsimile, so with this modem, +you can send document and scanned images as a Fax, as well as receive Faxes. +It supports BitFAX by Bitcom and any other 3rd party FAX software which +uses the standard CCITT AT-FAX command set. +A Data Compression called CSP (CompuCom Speed Protocol) is used to yield a +compression of up to 4:1, giving a throughput of up to 38400 bps. +This however, like MNP5 will not be effective when transferring compressed +files from BBS's, such as ZIP files. + +DIS and CPS are proprietary methods owned by CompuCom, Sunnyvale, CA. +Because this modem is inexpensive more people can afford to buy it, and since +its both a FAX and a Modem in one, it should gain popularity quickly. +It is still a new product, but hundreds of BBS's are showing support for it. + +----------------------------------------------------------------------------- + What Next? + +By mid 1991 the V.32bis standard will be finalized, and by that years end +the several 14,400 Bps full duplex modems will be on the market. +There is already talk of the CCITT releasing another standard in 1992, +which will be for 192,000 bps. Since these modems are expected to cost +considerably more then the V.32s currently on the market, they will be +out of the price range of most BBS users. + +----------------------------------------------------------------------------- + + + WHAT TO LOOK FOR + +THROUGHPUT: +========== + +You'll see ads claiming that you can attain 19,200 bps or 38,400 bps +with a 9600 Baud modem - this is true only if you are using MNP5 or other +form of data compression on an uncompressed data or text file. Any 9600 Baud +modem using compression will transfer at that effective rate. +But for BBS use, where files are already compressed (such as ZIPs, LZHs, GIFs) +MNP5 will actually slow down throughput by attempting to compress a file that +is already compressed. Generally when using a modem for BBS transfers, its +the RAW speed of the Modem and not the throughput which is important. + +Figures of around 1700 cps by the HST modems are attained through proprietary +methods not available on other modems. + + +CONFIGURABILITY: +================ +In High Speed Modems, there is a lot more to configure than on a 2400 Baud +modem. Be sure your modem comes with NRAM (Non-volatile Random Access Memory) +that can store your modem configuration, making long init strings unnecessary. +Also many modems have dip switches to set the default configuration, which +also simply things. If you buy an Internal Modem, be sure its fully +Configurable as far as selecting the com port and IRQ (interrupt request) +setting. Some modems can be addressed from Com1: up to COM8: + + +UARTS +===== +Internal Modems have a serial port built in, and External Modems use an +existing Serial Port in the computer. A serial port has a UART chip to buffer +and control the Input/Output (I/O). The XT usually has an 8450 UART which will +handle up to 9600 Baud. The AT usually has the 16450. If you have an external +modem you should replace your UART with the 16550 (NS16550AN). + + +INTERNAL or EXTERNAL +==================== +MS-DOS Users can choose internal modems, that plug in a computers slot, +or external, which plugs into an existing serial port with a serial cable. +Internals are usually less expensive, take up less space, have the correct UART +already installed (see below) and don't need a cable. But the Externals usually +have a lot of little lights on it that you can stare at, and its easier to move +to another machine. So which ever you prefer (or is available in some cases). + + + +If Considering a USRobotics Modem +================================= +You only need to worry about weather you want the HST +(which can be upgraded later), or the Dual Standard +which is the same modem with the V.32bis option included. + + +If Considering a V.32/V.42 Modem +======================================== +Some questions to ask: + +Can you afford the USR "DS" instead? +Is it both V.32 and V.42 compatible? +Is it V.42 compatible, V.42 compliant, or V.42bis? +If its not V.42bis or compliant, can it be upgraded? +Do Local/National BBS's support it? +Would you rather wait a year for a V.32bis? +What is the warranty? 5 years? + + +If Considering a FAX/Modem +============================== +some questions to ask: + +Is it Send and Receive Fax? +Does it support 3rd party FAX software? +Is it 4800 or 9600 bps? +Does it support MNP? +Does it support other compression? +Do Local/National BBS's support it? +What is the Warranty? 5 Years? + +--------------------------------------------------------------------------- + + + Modem Compatibility Listing: + ============================ + + +These modems will usually be downwardly compatible with 2400 Baud and slower +modems, Which means they are also CCITTY V.22bis and Bell 103/212A compatible. +Most have an auto-fall back mode that will detect the highest negotiable Baud +rate, which can either through hardware or software configuration. +If the modem is V.42 capable, it will fall back to MNP if the other modem is +not LAP-M capable, but is MNP capable.

Recently, however, several manufacturers have +creatively combined relatively mature techniques of data transmission with +newer technology and have introduced 9600 bps modems. + +Unfortunately, a widely accepted standard for full duplex 9600 bps +transmission as defined by the International Consultative Committee for +Telegraphy and Telephony (CCITT) does not yet exist (the CCITT is currently +considering proposals for a new 9600 bps dial-up standard). This means that +today's 9600 bps modems do not offer cross-manufacturer compatibility. The +CCITT HAS endorsed a half duplex and a full duplex 9600 bps standard, but to +date implementations of these relatively flexible standards have been +proprietary, i.e., even the "standardized" modems from different manufacturers +are not compatible. + +All this means that modem users who want to enjoy the dream speed of 9600 bps +must weigh the pros and cons of each 9600 bps technique before committing to a +particular 9600 bps design. This paper was written in an effort to provide +typical modem users with enough technical information and insight that they +will be able to consider the new 9600 bps modems from the position of an +educated consumer and not have to rely on information gleaned from sales +brochures and advertisements. It should be noted that the author, Wes Cowell, +is an employee of USRobotics. + + THE ROAD TO 9600 + +High speed data communications via the dial-up phone network is limited by the +available phone line bandwidth and by random channel impairments. Just as the +diameter of a pipe limits its liquid flow capacity, so does the telephone +channel bandwidth limit its data flow capacity. + +The roughly 3000-Hz available in the telephone bandwidth poses few problems +for 300 bps modems, which only use about one fifth of the bandwidth. A full +duplex 1200 bps modem requires about half the available bandwidth, +transmitting simultaneously in both directions at 600 baud and using phase +modulation to signal two data bits per baud. "Baud rate" is actually a +measure of signals per second. Because each signal can represent more than +one bit, the baud rate and bps rate of a modem are not necessarilly the same. +In the case of 1200 bps modems, their baud rate is actually 600 (signals per +second) and each signal represents two data bits. By multiplying signals per +second with the number of bits represented by each signal one determines the +bps rate: 600 signals per second X 2 bits per signal = 1200 bps. + +In moving up to 2400 bps, modem designers decided not to use more bandwidth, +but to increase speed through a new signalling scheme known as quadrature +amplitude modulation (QAM). + +In QAM, each signal represents four data bits. Both 1200 bps and 2400 bps +modems use the same 600 baud rate, but each 1200 bps signal carries two data +bits, while each 2400 bps signal carries four data bits: +600 signals per second X 4 bits per signal = 2400 bps. + +A technique known as adaptive equalization enables 2400 bps modems to adapt to +phone line impairments call-by-call. Essentially, if the modem is experiencing +problems with a noisy line, it looks for a "sweet spot" in the bandwidth and +attempts to avoid troublesome frequencies. This technique makes 2400 bps +modems more tolerant of line noise than their 1200 bps counterparts that use +compromise equalization (a one-size-fits-all approach). + +While these advanced modulation and equalization techniques in 2400 bps modems +provide for double the data rate of 1200 bps modems, they also result in a +design at least four times more complex than 1200 bps modems. + +Which brings us to the problem of designing a 9600 bps modem. + +Jumping to 9600 from 2400 bps is several orders of magnitude more complicated +than going to 2400 from 1200 bps. Telephone network characteristics make it +highly unlikely that success will be had in extending the "data signal +alphabet" (number of bits represented by each signal) beyond four bits per +signal. + +Instead, modem designers must increase the bandwidth that is to carry the +signal, and this presents a very big problem. In fact, at speeds of 4800 bps +(1200 signals per second), the transmit and receive channels must be expanded +to the point where they actually begin to overlap. A 9600 bps "band" +requires roughly 90 percent of the available bandwidth, making it impossible +to have two-way communication without the bands interfering with each other. + +A helpful analogy to the problem might be to consider a two lane highway: +traffic must flow in both directions simultaneously, but to carry more cars +per unit of time, highway designers must either increase the number of lanes +in each direction or widen the two lanes to accommodate driver error with a +margin of safety. Unfortunately, these options are not available to modem +designers as the available bandwidth is of a fixed size. + +With these considerations and limitations in mind, let's examine three basic +ways to accomplish full duplex (two-way) 9600 bps communications: echo +cancellation, virtual full duplex (achieved by half duplex systems), and +asymmetrical frequency division. + + ECHO-CANCELLATION + +This method solves the problem of overlapping transmit and receive channels. +Each modem's receiver must try to filter out the echo of its own transmitter +and concentrate on the other modem's transmit signal. This presents a +tremendous computational problem that significantly increases the complexity +-- and cost -- of the modem. But it offers what other schemes don't: +simultaneous two-way transmission of data at 9600 bps. + +The CCITT "V.32" recommendation for 9600 bps modems includes echo- +cancellation. The transmit and receive bands overlap almost completely, each +occupying 90 percent of the available bandwidth. Measured by computations per +second and bits of resolution, a V.32 modem is roughly 64 times more complex +than a 2400 bps modem. This translates directly into added development and +production costs which means that it will be some time before V.32 modems can +compete in the high- volume modem market. + +Despite the fact that V.32 is a recognized standard, it is uneconomical and +unnecessarily complex for personal computer datacomm applications that simply +don't require simultaneous two-way 9600 bps transmission. + + HALF DUPLEX SYSTEMS + (Virtual Full Duplex) + +Half duplex solutions devote the entire bandwidth to 9600 bps in one direction +at a time, and "ping-pong" the data flow back and forth to simulate full +duplex. This is potentially the simplest scheme. Its performance is +acceptable in data transfer applications that don't involve user interaction, +i.e. file transfers. Even so, advanced error-control protocols that require +ACKnowledgments to be sent in response to received data blocks generate a high +number of "line reversals" which greatly impair overall data throughput. In +short, the benefit of higher speed is so significantly compromised by line +reversals in half duplex sessions that the net gain in data throughput may be +marginal at best. + +If users want to operate in an interactive mode, their data must be sent to +the remote computer, the data channel must be reversed, and then the data must +be echoed back. This process results in significant turn-around delays which +can be very frustrating to users. + +Half duplex modems of this kind are most often based on CCITT recommendation +V.29 for half duplex 9600 bps transmission on the dial-up network. V.29 based +data pumps used in facsimile systems are available as LSI chip sets, providing +a short-cut to modem manufacturers, particularly to companies that don't +develop their own modem technologies. But the major problem is that the V.29 +modulation scheme has been outdated by the fact that it operates in a half +duplex mode and doesn't provide good signal to noise performance. The V.32 +recommendation, which operates in a full duplex mode and employs Trellis +Coding Modulation offers greater throughput and a greater immunity to channel +impairments. + +To the best of my knowledge, modems employing V.29-based modulation include +products from Racal-Vadic, Comspec, Develcon, Gamma Technology, Microcomm, and +Electronic Vaults, Inc. (EVI). These modems, however, are NOT mutually +signal compatible -- cross-manufacturer compatibility does not exist. + +Another modem in the half duplex category, but not based on V.29 modulation, +is the Telebit Trailblazer (R), which uses a proprietary modulation method. + +Trailblazer is based on a multi-carrier technique. Conceptually, the +transmission channel is divided into many (512), independent, very narrow +channels (think of our two-lane highway and imagine it as having 512 very +narrow lanes (say, for bicycles) going in one direction and you've got a fair +idea of how Trailblazer divides the bandwidth). The main advantage is that no +receiver adaptive equalizer is needed because each channel is very narrow +compared to the overall channel bandwidth. + +Further, in the Trailblazer modulation scheme, the modulation rate in each +narrow channel can be changed somewhat independently. Trailblazer is +different from many other modems in that the decision to fall back to lower +speeds is built into the modem protocol, rather than controlled by the user's +computer port. It is claimed that in the face of channel impairments, +throughput can be adapted gracefully to channel conditions. Traditional +modulation systems would have to fall back in larger steps. But there are +three inherent MAJOR problems: + +1) The turn-around delay is very long compared to conventional modulation +techniques because data must be sent in large blocks. A typed character may +take several seconds to be echoed back to the system that sent it. As a +result, the system fails to achieve the illusion of full duplex and is not +really suited to interactive online sessions. + +2) The Trailblazer receiver cannot "track" carrier "phase jitter" (phase +jitter can be thought of in terms of "phase shift": think of how the whine of +a race car goes from higher to lower as it passes the viewer -- the frequency +of the sound is said to be "shifted" or "jittered"). Instead of cancelling +out phase jitter (which is commonly encountered on long distance calls) the +Trailblazer can only respond by lowering throughput to gain more immunity to +phase jitter. + +3) The ability to transmit at the maximum rate when subject to channel +impairment is considerably less than for conventional modems. There is one +notable exception: the multiple channel technique offers extremely good +immunity to impulse noise because the impulse energy is distributed over +narrow channels. While conventional modems can achieve similar results +through special coding or filtering techniques they rarely implement such +methods. + + ASYMMETRICAL FREQUENCY DIVISION + +When one considers the nature of most PC datacomm applications, it is realized +that most applications are interactive, involving manual (typed) data entry +from one end and data file transmission from the other end. + +Few, if any, PC users can justify using an expensive 9600 bps channel to carry +their typed characters when they realize that 300 bps translates to 360 words +per minute. Assuming one could type 100 words per minute, even a 100 bps +transmission channel would be sufficient. + +On the other hand, file transfer should take advantage of the tremendous speed +of the microprocessor. Serial ports are often set at data rates in excess of +19,000 bps. + +Considering these inherent characteristics, a communications scheme that +incorporated a high speed and a low speed channel would be best suited for +most PC datacomm applications. + +Remembering the highway analogy (higher speeds mean wider lanes), one can see +how such a method would grant modem designers a large portion of the +available bandwidth for a 9600 bps channel and still leave enough room to +accommodate a narrow 300 bps channel without any channel overlap. + +By utilizing two discreet channels, such a modem would avoid costly, complex +echo-cancellation schemes. And, because the channels carry data in both +directions simultaneously, the communications link is a true full duplex +connection. This means that data entered at one system would be almost +instantaneously echoed back -- eliminating the frustrating turn-around delay +experienced in half duplex sessions. + +USRobotics has developed just such a modem. It passes data in one direction +using the V.32 modulation technique (a very robust method that is very immune +to phone line impairments) but employs only a 300 bps channel in the opposite +direction so that the channels do not overlap and echo-cancellation is not +necessary. + +The use of the high-speed channel by the two modems is based on data demand. +In most applications, however, "channel swapping" will not be required. For +interface elegance, the modems employ a 4K buffer that allow them to perform +data rate conversion: sending and receiving speeds remain constant between the +modem and the computer -- it is only in between the modems that transmitted +and received data run at different speeds. + +For interactive sessions, users are assigned the low-speed channel while the +data sent to them (long mail messages, menus, files, etc.) in the 9600 bps +channel. + +For file transfer sessions, the data blocks that make up a file are sent in +the 9600 bps channel while the corresponding ACKnowledgments are returned in +the 300 bps channel. An asymmetric frequency division scheme is ideal for +file transfer where large data blocks (usually several hundred bytes in +length) are transmitted in the high-speed channel and the ACKs (usually only +a few bytes in length) are carried in the low-speed channel. + +If a user switches from an interactive mode to file transfer and then back to +interactive mode, the high speed channel is dynamically and automatically +assigned to the system with the greatest data demand. + + A BRIEF COMPARISON + +Three options exist for data communicators who desire to operate at 9600 bps: + +1) V.32-type modems offer a full duplex connection but do so by virtue of +echo-cancellation. This technique is so complex, and has proven so difficult +to employ, that the cost for such modems will remain prohibitively high and +their implementation a delicate task for some time to come. + +2) Half duplex modems (either V.29 or multi-carrier) offer 9600 bps but the +turn-around delay inherent in half duplex links severely compromise overall +throughput. This degradation of throughput, however, can be more than offset +by data compression techniques assuming the modems in question support +identical compression protocols and are operating on relatively "clean" phone +lines. Both half duplex methods suffer disproportionate degradation on +"noisy" lines: the V.29 modems must spend more and more time in line reversals +as detected data errors increase, and the multi-carrier modems must sacrifice +throughput to gain noise immunity. + +3) Asymmetrical Frequency Division offers 9600 bps communications in a true +full duplex implementation. By efficiently utilizing the available bandwidth, +these modems provide users with high speed file transfer capabilities and fast +response in interactive sessions. Because the transmit and receive data +channels do not overlap, expensive echo-cancelling techniques are unnecessary +making these modems economically efficient. + + IN CONCLUSION + +Until a widely recognized standard is agreed upon by the standards community, +and implemented by several manufacturers, modem buyers must weigh the benefits +and detriments of each 9600 bps scheme. + +V.32 would be best where symmetrical, full duplex, synchronous communication +is desired (for example, dial-up HDLC links between multiplexers) and where +the user can modify his software to accommodate non-"AT" command-driven +modems. + +V.29 modems would be likely solutions where absolute lowest price is required +and conformance to an international standard (in a very limited sense) is +desired. + +Multi-carrier transmission schemes are well-suited to applications that +require maximum one-way throughput and where circuit conditions are known to +be good. This transmission method is also ideally suited for circuits where +immunity to impulse noise is paramount. + +Users who most often work with one-way file transfers (PC-to-PC) or with real- +time applications may opt for an Asymmetrical Frequency Division scheme, which +is suited equally well for either application. The elegant approach to the +frequency division (avoiding overlapping bandwidths) also allows these modems +to present a very economical ratio between dollars and bps. + +Potential high-speed-modem buyers should also consider the aspects of ease-of- +use, ease-of-implementation, and downward compatibility with existing +implemented standards (the CCITT's V.22bis for 2400 bps, Bell 212A for 1200 +bps, and Bell 103 for 200 bps). + + POST SCRIPT + +Many modem users have voiced confusion and consternation about the lack of +compatibility between modem manufacturers at speeds greater than 2400 bps. + +Modem manufacturers have embraced the Bell 212A and 103 standards for 1200 and +300 bps. In these post-divestiture days, however, Bell no longer sets modem +standards in the U.S. and hence, U.S. modem manufacturers have turned to the +CCITT as a definitive source for standards. The industry-wide acceptance of +the CCITT's V.22bis standard for 2400 bps is the best example of this shift. + +The CCITT recommendations V.29 and V.32 for 9600 bps have not resulted in +compatible implementations. It is important to remember that V.29 was +originally developed as a four-wire full duplex leased-line modem and has +since been adapted by various manufacturers to encompass half duplex dial up +applications. Other problems with V.29 are that it compromises transmission +speed and is poor for interactive sessions. V.32 is proving to be +prohibitively complex and exceptionally difficult to implement (driving +development and production costs up). + +Recognizing the need for an alternative to the V.32 recommendation, the CCITT +has requested proposals from modem manufacturers. + +Presently, two proposals are being considered by the CCITT. One is the multi- +carrier scheme developed and sponsored by Telebit. The other is an +Asymmetrical Frequency Division scheme developed and sponsored by USRobotics. + +  diff --git a/textfiles.com/computers/ASTRESEARCH.1 b/textfiles.com/computers/ASTRESEARCH.1 new file mode 100644 index 00000000..8392cc5f --- /dev/null +++ b/textfiles.com/computers/ASTRESEARCH.1 @@ -0,0 +1,542 @@ + +T E X T F I L E S + +

User's Manual shows the correct switch + settings for Switch Block #3 on the Advantage! in a 256K AT. + (In a 512K AT, you may use either Split or Contiguous Memory + Addressing on the Advantage!) + +* The AT system board may be equipped with either 256K or 512K + installed. A jumper on the system board (J18) determines the + maximum amount of memory the system board will accept. With + the jumper in one position, the system board will accept a + maximum of 256K, while in the opposite position, the system + board will accept a maximum of 512K. IBM ships some 256K ATs + with this jumper in the 512K position. This means that in + such a 256K AT, there is an additional "phantom" 256K memory + block present. When the Advantage! is then installed, its + memory will conflict with this "phantom" 256K block on the AT + system board. The usual symptom of this problem is an error + during power on self test such as "040002...201". + +* To avoid this memory addressing conflict, before you install + the Advantage! in a 256K AT, verify that the jumper on the AT + system board is in the correct 256K position. The jumper is + identified as "J18" and is located underneath the disk + controller card at the very front of the AT chassis. It may + be necessary to lift the disk controller card up in order to + gain access to the jumper. + + + +NOTE: As a portion of the data is in pictorial form, it is not + included here.

Problems may +occur if the interrupt takes a longer time to be serviced than +the communication software expects. + +For this reason, AST suggests that the AST board is set for an +unused non-cascading interrupt. + +The following AST communication packages use IRQ2: AST-5251/11, +AST-5251/12, AST-3780, AST-3770, AST-BSC, AST-BSC CLUSTER, AST- +BSC GATEWAY, AST-SNA, AST-SNA CLUSTER, and AST-SNA GATEWAY. + \ No newline at end of file diff --git a/textfiles.com/computers/ASTRESEARCH/0152.tb b/textfiles.com/computers/ASTRESEARCH/0152.tb new file mode 100644 index 00000000..148143f7 --- /dev/null +++ b/textfiles.com/computers/ASTRESEARCH/0152.tb @@ -0,0 +1,12 @@ +AST RESEARCH TECHNICAL BULLETIN TB-0152 2-19-86 + + + AST-5251/11 WITH AT&T 6300 USING DISPLAYWRITE 36 + + +When configuring an AST 5251/11 board in an AT&T 6300 or 6300 +PLUS, it is suggested to configure the workstation on the host as +a 5251/11, not a 5291 or 5292.

The user simply needs to boot the DESQview +program on an OLD PC or AT and create a "script" (macro) to +reassign the ALT key to another keystroke, such as the grey "+" +key. He should do this in a DOS window under DESQview, which he +will save as the file "D1-SCRIPT.DVS". Then all he has to do is +make copies of the file, one named DESQVIEW.DVS and another for +each of the programs he'll be using under DESQview - +"LT-SCRIPT.DVS" for Lotus, "D2-SCRIPT.DVS" for dBASEII, and so +on. These should all be stored in the DESQview subdirectory +(\DV) and he's ready to go. + \ No newline at end of file diff --git a/textfiles.com/computers/ASTRESEARCH/0198.tb b/textfiles.com/computers/ASTRESEARCH/0198.tb new file mode 100644 index 00000000..8a15faa3 --- /dev/null +++ b/textfiles.com/computers/ASTRESEARCH/0198.tb @@ -0,0 +1,36 @@ +AST RESEARCH TECHNICAL BULLETIN TB-0198 6-26-86 + + + RECEIVING A FILE USING AST 3780 + + +The purpose of this Technical Bulletin is to assist users of the +AST 3780 package with the following symptom: The PC is unable to +receive a file from the host.

THINGS TO CHECK BEFORE RUNNING EMULATION + + A. Computer Checks + + 1. DOS 3.20 has been known to cause problems, try to + stay away from using it. DOS 2.1-3.1 and 3.3 works + well. + + 2. What kind of PC? + + a. IBM PC, XT and compatibles (using 8088 or 8086 + processors) - If a hard disk exists, IRQ5 and I/O + address range 320-32F cannot be used. + b. AT and AT compatibles (using 80286 processors) - + IRQ5 is used by second parallel port (LPT2), if + existent. + c. Some clone computers might not work with AST's + emulation board. Try changing IRQ's and I/O + addresses. + + 3. How much memory does the computer have? + + a. Need 256K minimum for emulation. + b. Need 512K minimum for emulation with file + transfer. + c. Need over 256K to run CFG5251.EXE for DOS + versions 3.0 and up. + + 4. What does the computer have? + + a. If the computer has a serial port utilizing COM1, + IRQ4 cannot be used. + b. If the computer has a serial port utilizing COM2, + IRQ3 cannot be used. + c. Some real time clocks may use IRQ2. + d. If the computer has a hard disk, I/O address + range 320-32F and IRQ5 cannot be used (does not + apply to AT or AT compatibles). + + B. AST-5251/12 Emulation Board Check + + 1. Ensure no other board or device is using the IRQ and + I/O address of the 5251/12 board. Change these + switches and corresponding software configurations if + a conflict is encountered. + + 2. DTE mode: (going through a modem) + + a. Ensure the shunts on the top-right corner of the + board are on positions U25 and U27. + b. Make sure the "shorting plugs" (jumpers) on the + board are on pins 1 and 3 (8 is not necessary). + c. If an IBM, UDS or AT&T modem is used, some hardware + modifications must be made. Remove the shunt from + position U25 and bend pins (legs) 3 and 6 on the + top row so that they will not make contact with the + board when put back. + d. The baud speed jumper is not used and does not have + to be set. + + 3. DCE mode: (no modem used) + + a. Ensure the shunts on the top-right corner of the + board are on positions U26 and U28. + b. Make sure the "shorting plugs" on the board are on + pins 2 and 4 (8 is not necessary). + c. Select the baud speed with the baud rate jumper. + + C. CFG5251 Configuration Program Check + + 1. If PC Support or PC FSU is being used, make sure IBM- + API is ON. + + 2. Ensure the hardware configurations in CFG5251 + HARDWARE, corresponds to the actual hardware settings. + + 3. Ensure the NRZI and SDLC settings match the host's + configurations. + + 4. Select the correct BPS (baud per second) speed for the + specific modem being used. + + 5. If using a color monitor change DSP_ADAPTER type to + COLOR, NOSNOW. + + 6. Ensure correct station address(s) is set in the + STATION option. Address 0 must be a 5251/12 on both + the PC and host (cannot be defined as a 5294 + controller). If other sessions are being used, the + device type must match the device type configured on + the host. + + 7. If using a printer other than an EPSON, IBM, NEC, or + DIABLO, the correct hex codes must be entered in the + OPTIMIZATION option. These codes can be found in the + manual for the specific printer. + + D. Miscellaneous Check + + 1. DTE and DCE mode + + a. Make sure modems being used are synchronous. + b. Ensure RS-232C is a 25 pin straight through cable + (must have at least 11 conductors: 1, 2, 3, 4, 5, + 6, 7, 8, 15, 17, 20). + + II. THINGS TO CHECK WHILE TRYING TO BRING UP EMULATION + + A. Computer Locks Up As KERNEL Or APS Is Running + + 1. IRQ conflict. Resolve conflict by changing IRQ on + CC-432 or removing device that is conflicting with the + emulation board. Could also be an I/O address + conflict. + + 2. Delete AST5251.CFG file and create a new one. + + 3. Run emulation from floppy if currently using hard + disk; copied files might be corrupted. + + B. Goes Through KERNEL and APS But No SA (System Available) + + 1. Check cable and connections between modem (DTE mode) + or host (DCE mode) and PC. Make sure all necessary + pins exist. Use a cable that has been verified to be + good. If no other cable is accessible, use a + continuity test to check connections. + + 2. Check that the session(s) defined in the CFG5251 + program matches host configurations. The host must be + IPL'ed after changing configuration to make changes + valid. + + 3. Ensure the modems are good by having them tested or + use a modem that has been verified as working. + + C. Gets SA (System Available) But No Sign On Screen. + + 1. Ensure all error messages on the system console have + been responded to. + 2. Ensure device type of PC matches host. Cannot be + configured as a 5294 controller nor address 0 as a + printer. + + 3. Press - for regular keyboards + (83/84 keys), or - for + enhanced keyboards (101/102 keys). + +III. HINTS FOR ISOLATING PROBLEMS + + A. Have only the AST-5251/12 board and the boards absolutely + necessary (monitor and disk controller) in the PC. This + will give a good indication of whether the board is good + or not, and whether the board is compatible with the + specific computer. + + B. Have the customer dial into AST's System/36 to see if the + computer and modems are configured properly and working. + If able to sign on to our system, the computer, modem, + cable and emulation card is good and the problem lies in + the customers host system. If customer was not able to + sign on, there is a problem on the customers site, either + with configurations, modem, cable, a bad board, or a bad + computer. + + C. Swapping devices: PC's, boards, modems, cables and any + other device that may affect the workability of the + emulation board is very useful for finding the source of + a problem. + + IV. PROBLEMS WHILE EMULATION IS RUNNING + + A. "Error Reset" key does not function. Keep Error Reset + key down for 3 seconds. + + B. Transferring enhanced keyboard file. + + 1. Put copy of diskette 2 of 2 into drive A. + 2. Run ASTKBD from drive A. + 3. Select desired path. + 4. Select keyboard file UNITED_S.ENH. + + C. Printer prints but not in correct format (i.e., extra + line-feeds, compressed mode ...) + + 1. Enter correct printer hex codes for LINES/INCH, + CHAR/INCH, RESET and VMI (vertical motion index) under + the OPTIMIZATION option in CFG5251. These codes are + found in the printer manual for the specific printer. + D. Snow on color monitor screen. Change DSP_ADAPTER type to + COLOR, NOSNOW. + + E. Sign on screen is very dim. + + 1. Change DSP_ADAPTER type to COLOR COMPOSITE, NOSNOW. + 2. If computer is an AT&T 6300 or PS/2 model 30 change + DSP_ADAPTER to COLOR COMPOSITE, NOSNOW and give + display ATTRIBUTE fix (attached). This fix could also + correct dim display problems for other computer types. + + F.

The NRZI option is host (IBM System 34, 36, 38 or AS/400) + controlled. This is IBM's error correction detection system. + It is either ON or OFF. The user must verify this parameter + with the host's system operator. + + 14. Under the TRACE option these options will be displayed: + + NONE SNA SDLC QUIT + + Note: It is recommended that the TRACE option be used as this + is a good trouble shooting tool. With this option + selected the user will observe a fixed set of numbers + followed by incremental numbers on the bottom left and + right hand corners of the display during emulation. + The numbers on the left bottom corner indicate that the + AST package is receiving data from the Modem and the + numbers on the right bottom corner indicate that the + AST adapter is transmitting data to the Modem. + + If there are no numbers at either corner then it + indicates that the Modem is not communicating with the + AST CC-432 Adapter. Several probable causes for this + occurring are as follows: + + A. Bad or wrong type of cable connecting the Modem to the AST + CC-432 Adapter. User could be using a standard + asynchronous null Modem RS-232 cable that does not have + pin 15 (transmit clock) and pin 17 (receive clock) + connected. + + B.

The NRZI option does not match between the host and AST + 5251/12 Emulation. + + 15. Highlight SDLC and press [Enter]. This is the controller + station address configured at the host (IBM System 34, 36, 38 + or AS/400) site. The user must verify this parameter with the + host's system operator. It is a hexidecimal value and ranges + from 01 through FE. Enter the appropriate value and press + [Enter]. + + 16. Press the ESC key and then highlight DSP_ADAPTER and press + [Enter]. Highlight DSP_ADAPTER on the next screen and press + [Enter]. Next highlight the type of display adapter you are + using and press [Enter]. Example: "Color". + + 17. Press ESC until you return to the EDIT 5250 CONFIGURATION + menu. Highlight STATION and press [Enter], the following list + will appear: + + 0 2 3 4 5 6 7 8 9 QUIT + + 18. Station Address 0 will always be configured as a 5251/12 + display type. This cannot be changed. Station Address 1 is + reserved for SNA and is not available. The address scheme for + the AST 5251/12 Station Addresses and the IBM Host Addresses + are as follows: + + STATION option (AST) 0 2 3 4 5 6 7 8 9 + Ports on IBM 0 1 2 3 4 5 6 7 8 + + Respectively for an IBM 5251/12 (what AST is emulating) remote + controller where all device codes are configured for + workstation address 0.

Press the ESC key until you return to the EDIT 5250 + CONFIGURATION menu. Highlight STATION and press [Enter]. + + 8. STATION ADDRESS 0 is already configured for you. + + ADDRESS 0 - 5251/11* DISPLAY IBM-API: OFF + (NO SESSION NAME) + + *The device type can also be a 5291-1 or a 5292-1. + + For this setup you do not need to delete or reconfigure. + Address 0 on the MASTER PC is taken by the 5251/12 Controller + so this SLAVE PC configuration would then go to the next + available session on the MASTER PC which would be address 2. + + Note: We are setting this up for "session bidding", therefore + we do not need to configure the exact station address + for the slave. When the slave software is executed, it + looks at the master configuration to see which gateway + display is available. This is called session bidding. + This is how all the slave configurations should be set + up for session bidding. + + 9. Press the ESC key until you return to the AST 5250 + CONFIGURATION menu. The user will now save the SLAVE PC + configuration settings and exit to DOS. + + 10. Highlight SAVE and press [Enter]. + + 11. The program will ask "Save configuration file: AST5251G.CFG + (Y/N)?" Respond (y)es and press [Enter]. + + 12. Highlight QUIT and press [Enter]. + + 13.
