I don't think all those "set back" thermostats are a sham - thus I think
|
|
it IS appropriate to set back air conditioning when a location is not
|
|
occupied. Lets take the worst case of a house unoccupied for a month's
|
|
vacation. Surely the AC shouldn't be left on 78 degrees all that time. It
|
|
won't cost THAT much - perhaps 4 hours operation - to bring the house to
|
|
76 degrees after the people come back. At the other extreme is the
|
|
idea of leaving the AC on full time. That would be most expensive. I'm
|
|
sure there is some formula for determining the optimum - for example "don't
|
|
go more than 8 degrees high" or something.

Here's what a 720K disk looks like:

Defaults to A: drive, or specify a drive: DiskParm c:

512 bytes per sector

|
2 copies of fat

|
112 root entries

|
1440 sectors per disk

F9 media descriptor

|
3 sectors per fat
|

9 sectors per track

2 heads

0 hidden sectors

|
|
So, no a 720K isn't 512 byte clusters - it is 1K.
|
|
720K floppies could even be patched to use 512 byte clusters, but
|
|
you'd have to increase each fat's size, move the root dir down, etc.
|
|
Major process, but I've done it as an exercise.

A light bulb doesn't fail due to the start-up spike. It fails during
|
|
start-up due to thermal shock - going from room temp to thousands of
|
|
degrees. Nevertheless this same cold-to-hot transition, to a lesser
|
|
degree, obviously applies to electronics.

to ALL re: HOW A PC BOOTS
|
|
|
|
I'd been asking (not here) how a PC boots, and found the following, by
|
|
pointers to the MS-DOS encyclopedia.
|
|
What happens is that the rom goes to the master boot sector (MBS) of
|
|
the drive, and looks for the following:
|
|
- can read it (obviously - if it can't read it it hasn't been LLF'd)
|
|
- finds a long or short JMP in byte 0
|
|
- finds a 55 AA at the end of the sector
|
|
...THEN it loads that code into 0:600 (I think) and executes it. It moves
|
|
itself up, sets up pointers to the partition, and then loads the boot
|
|
sector from DOS or what ever is set up to boot. It loads up at 0:600 also.

to WARD CHRISTENSEN re: R/HOW A PC BOOTS
|
|
|
|
Good description, except that the code I've looked at executes at
|
|
0:700. The partition sector (C0H0S1) on a hard drive is an executable
|
|
code fragment which finds the active partition's first sector, loads IT
|
|
and executes it to complete the beginning of the boot sequence. It
|
|
can be very instructional to disassemble C0H0S1 on a standard, FDISKed
|
|
hard drive to see that part in gory detail.

Ahh... your right about thermal shock to a light bulb, but it also
|
|
does gets spiked as well. Light bulbs when cold hardly offer little
|
|
resistance to electrons. On the other hand, when they are heated to
|
|
high temperatures with the combo of mass current flow, starts to
|
|
oppose current flow and builds up lot more resistance.
|
|
|
|
On a different note, filaments in tubes, which act very much like
|
|
light bulbs, would usually blow (if connected in series) either the
|
|
one in the path of an incoming electrons or the one rated at the
|
|
highest voltage drop. Knowing this little trick while repairing
|
|
tube TV sets with series connected filaments which had one or more
|
|
filaments gone proved very helpful.
|
|
|
|
In short, yes you are correct in what you are saying, but there
|
|
are also mass surge that builds up through a filament when you first
|
|
turn it on or shall I say whenever you turn it on.

Ah... that old MS-DOS bug got me again. I had a open file on drive B:
|
|
and swapped the data disk with a freshly formatted disk. I forgot that
|
|
there was an opened file on the other disk and placed the old data
|
|
disk back into the drive and then read the directory and wham! The old
|
|
directory is now replace with the formatted disk with no files. OH
|
|
NO!!!
|
|
|
|
I recovered some files with RECOVER and CHKDSK MS-DOS commands, but
|
|
those that were much older than a few days were all gone. Why oh why
|
|
does this bug still exist while many never warn you of this. Ouch!

I ran into the old "change the disk with open files" 3-5 times at work-

I used to say I would rebuild the disks for 'em - but after about 5 hrs
|

hacking, I decided it wasn't worth it - better to teach 'em "don't do it!".

When DOS 4 came out, and showed this funky serial #, I said "Yay! At

Everyone seems to be talking about whether to leave power on the computer
|
|
or turn the whole thing off when leaving it. To cover the monitor, let me
|
|
say that the monitor should be shut off any time you're not going to be
|
|
using it for the next fifteen minutes.
|
|
I spent the better part of the period 1967 to 1978 repairing TV sets,
|
|
and found that sets left on all the time developed a peculiar weakness of
|
|
the CRT; it would be fine once on for a while, but when turned off and hten
|
|
on, it would take nearly forever to "warm up" to the point that it had even
|
|
a viewable picture (much less a good one).
|
|
How does this experience carry over? Take a TV, gut it (remove the tuner,
|
|
the IF stages, the video detector, the chroma stages, etc. etc.) and you
|
|
basically have a monitor. The Princeton HX-12 I'm using today was a
|
|
throwaway from a company that was told the CRT was bad; I soldered an
|
|
intermittent joint on a CRT driver transistor and it hasn't performed in

any less-than-perfect manner since.

The debate is open on leaving the computer on (I leave mine on 24 hrs.)
|
|
but the monitor should be turned OFF whenever you plan not to use the 'puter
|
|
in the next fifteen minutes (about the amount of life the CRT loses when
|
|
you turn it on).

Hi Cliff! Well I understand what your saying but many improvements have
|
|
been made since the 60's and 70's. There used to be a claim that leaving
|
|
CRT's on all the time with the same screen causes the image to be burned
|
|
into the screen. Since then, the screens can take lots more heat then the
|
|
older types. So this would hardly be a problem today. I have yet heard of a
|
|
case that this has happened with any CRT later than say 1980. Of course,
|
|
you can if you turn the bias higher than average viewing.
|
|
|
|
Another thing you have to worry about is the heater (filament) in the CRT.
|
|
If that goes (you have three filaments on a color CRT) you'll be out of
|
|
business (if color, you're out a color). Turning it on and off will weaken
|
|
the filament(s). Also leaving it on, will also weaken it. There is no
|
|
winning here, just balance.
|
|
|
|
I do still have a CRT rejuvenator that works wonders in some cases. It
|
|
won't fix broken filaments, but it will help getting a brighter picture.
|
|
Though this trick does weaken the filaments and can blow them during the
|
|
event. Darn if you do and darn if you don't.
|
|
|
|
Another thing helpful (or harmful depending how you look at it) is that
|
|
most CRT's now have a small voltage applied to the heater all the time.
|
|
This speeds up warming up a CRT and lessens the quick temperature changes
|
|
that a CRT has to go through. On the other hand, it's on all the time even
|
|
though on a lower setting sometimes.
|
|
|
|
By the way, I too, turn off my monitors if I won't be using them in about
|
|
15 minutes or so. I also turn off my computers most of the time too. Though
|
|
I don't have hard drives. If I did, I would likely leave mine on more. I
|
|
don't really dislike hard drives, it's just the computers I use would be
|
|
very expansive to add one.
|
|
No dup. chars.
