to BILL FISCHER re: R/CHINET DOWN?
|
|
|
|
About once a week, Randy has a system board memory parity error with
|
|
Chinet - which is running on a 20mhz 386.
|
|
Randy decided - "for speed freaks like you, Ward" (grin) to move his own
|
|
386/33 to Chinet, as he crashed Thurs nite.
|
|
Well, turns out his 4th drive just won't be recognized by Unix, though
|
|
DOS loves it. SO chinet was down for the transfer, testing, and eventual
|
|
restoration of it on the 20mhz system.

to ALL re: INTNL. SHAREWARE SOURCES
|
|
|
|
I'm writing an assigned cover-story article on "Shareware around the
|
|
World" for which I'll be soliciting viewpoints from individuals in
|
|
roughly 20 countries outside the U.S. on five continents. I'm looking
|
|
for leads to sources to expand my current list. Individuals needn't be
|
|
"experts" on shareware or have any particular qualifications other than
|
|
some connection to shareware. Sources may be everyday shareware end
|
|
users, dealers, BBS sysops, etc. The only real prerequisites are a
|
|
reasonable command of the English language and availability by voice,
|
|
modem or (preferably) FAX during July and August. I would welcome leads
|
|
to possible sources. Thanks.

Hi Murray! How does the getter continue to operate when the tube is off? Oh
|
|
you must mean when the cathode current is off. Where does the getter really
|
|
sit? And from what voltage does it operate from? Here is a crude drawing of a
|
|
CRT. Can you elaborate?

--------/ F B S C
|
|
|
|
F=Focus; B=Brightness; C=Cathode w/heaters times 3
|
|
|
|
Also from what I can gather, the shadow mask is the same surface as what the
|
|
high voltage is also applied to. And ground is applied to the coating just
|
|
outside the CRT, which makes a really big capacitor at high voltage. In this
|
|
case, it's 20KV, do I have this right so far? Now the barium isn't really in
|
|
the electron beam path per se, but must be a lower energy cloud of electrons
|
|
which focus' to the high voltage, correct? It would also make sense to fire up
|
|
a CRT from time to time to prevent the CRT from losing too much vacuum and
|
|
burn up the filaments. Also does the getter operate without filament voltage?
|
|
If so, then one would benefit by disconnecting the filaments first for a few
|
|
hours to 24 hours, if they believed the vacuum is bad. Is this so?
|

to CLIFF SHARP re: GETTER THEORY
|
|
|
|
Well Cliff, your sort of close about how a getter works but I believe your a
|
|
little side tracked. The idea isn't to coat the inside of the CRT to prevent
|
|
further leakage in, but rather to trap gases and stick them to the sides to
|
|
get them out of the way of the electron beam and to prevent oxygen (another
|
|
gas) from burning up the filaments. I suppose some coating of porous areas
|
|
(though glass isn't very porous) would take place, but not likely to be a big
|
|
benefit. Let's say if an air molecule happen to make it through the glass. I
|
|
doubt if a small amount of barium will continue to stop it. How our ion getter
|
|
pumps would work in our electron microscopes (a large CRT really) which it
|
|
appears CRT getters don't have was large magnetics (although the yoke might
|
|
work as one) to cause electrons (and I suppose atoms) to take a spiral path
|
|
instead of a straight one. Which would cover more area than a straight path.
|
|
Like getting two birds with one stone, so to speak. We also used titanium
|
|
instead of barium. Why I don't know? Maybe Murray has the answer! My guess
|
|
would be because titanium works better, but also cost a lot more. We are
|
|
talking about $150 for a CRT and $500,000 for an electron microscope. You can
|
|
add a few extras for that price. Our ion pumps claimed to have a life of
|
|
20,000 hours. Which was about 2 years at 24 hours per day. Though it seems to
|
|
me, they would work closer to 5 years (at 24 hours per day) as a general rule
|
|
(though some are still going after 10+ years). The poorer the vacuum, the
|
|
shorter they usually lasted. The shortest one would last about 2 years. Our
|
|
getters would operate with about 3KV and no heater. I don't think getters ever
|
|
used heaters, but Murray should know for sure. I understand that a getter was
|
|
invented only after they found out when they used a gauge for high vacuum
|
|
which was called a penning tube (or penning gauge), would actually start to
|
|
pump on small loads. Someone got the idea to make larger ones and then formed
|
|
what we now call a getter. Hey Murray! If the getter supply is isolated, one
|
|
could measure the vacuum in the CRT! I suppose measuring the current for the
|
|
high voltage while the tube is off would do it. Too bad we have no way to know
|
|
what current equals for what vacuum though!

to MURRAY ARNOW re: REFERENCE BOOK
|
|
|
|
Hi Murray! I know you may not be interested in electronics per se, but here's
|
|
a great reference book called "Horowitz and Hill: The Art of Electronics." It
|
|
takes a reader with no experience in electronics to a reasonable degree of
|
|
proficiency in electronic circuit design (really an expert by typical
|
|
researchers in the physical sciences). It is somewhat old (1980), but saved my
|
|
neck a number of times. It is published by Cambridge University Press and I
|
|
got my copy about 6 or 7 years ago at Kroch's & Brentano's for $29.95. Of
|
|
course, they had to special order it. By the way, the ISBN is 0-521-23151-5.
|
|
It doesn't have anything on tubes, just solid state devices. It does have a
|
|
lot on computers and even something on the RS-232 protocol.
|
|
No dup. chars.
