Dave-
My subject line included a question mark; I wasn't making a
declaration, I was posing a query...
Radio Shack sold these cleaning kits for years for, what, $5.95?
Now, and I don't know, perhaps RS doesn't sell them anymore. I
don't have a Jameco catalog handy to check, though I could look
at a Global catalog... at any rate, I'm wondering whether this
might have been a typo that the seller didn't catch...

Hardware wise the Infoserver 150 is a MicroVAX 3100 Model 10. Software wise
I never got any real chance to hack mine and ATM it's in my storage room
along with a VXT1200 X-terminal, which was the reason the 150 existed in the
first place - one of the popular DEC bundles of the day was an infoserver
and 5 VXTs. The software uses the Local Area Disk protocol (LAD/LAST) for
disk services which requires a client to be running on a VAX somewhere
(SYS$MANAGER:ESS$STARTUP.COM). VXTs could boot using IP/BOOTP/TFTP.
There must be more than just ROM changes to the hardware though.
I used to think that the whole reason the 150 came about in the first place
was that Digital had a small mountain of 3100/10s lying around so they did
their usual trick of using old hardware for new tricks (viz: RL02s as
console media for bigger VAXen (6xxx?), PRO380s as consoles for 8xxx's etc).
The 150 was superceded by the Infoserver 1000, which was smaller than the
RRD42s that it controlled.

Why is it that anytime anyone asks: "Does anyone in my small geographical
area have a 'foo' they want to get rid of?" there is invariably a slew of "I
have one, but don't want to get rid of it" or "I have one I want to get rid
of, but not in your area, and not willing to ship" messages?
If you're not in the area, or you don't want to get rid of it, why reply?
I mean it's gotta be annoying to the original poster to hear of others in
the area, with the "foo" he needs, but who don't want to get rid of it.
It's not bad that they have the "foo", but it seems like the reply is
rubbing his face in it....

Value is in the eye of the beholder, man. Why is it automatically
"insane" when someone else views omething as being more valuable than
we do?
The resale value of the stuff we hack on is going up, and we have to
learn to deal with it. It has been for some time. People are buying
it at these prices, and it's not just one or two people. Let them
spend their money...if they're happy with their purchase, what's wrong
with it?
Further, one mustn't lose sight of the fact that different things
are more readily available in different geographic areas than in
others. Just because there are fifty AppleIIs at the corner yard sale
in your neighborhood doesn't mean there are fifty of them at EVERY
corner yard sale.
As a case in point...I'm no newcomer to this field; I've been doing
pdp8/pdp11/vax stuff for a solid fifteen years. My first real system
was a pdp11/34 which I sold about ten years ago, and have regretted it
every since. I've wanted another one for several years, and had been
looking for one in earnest in the Washington DC area for a solid three
years...never managed to get one, and believe me, I know where to
look. I finally bought one locally for about $400, indirectly from a
surplus dealer who was sharking on the "antique computer craze" trying
to make a ton of money on it. I'm sure he got it for free, and he
laughed all the way to the bank. However, I'm VERY happy to have it,
and I love the machine. If I hadn't paid that $400, I wouldn't have
one. They're simply unobtainium in the DC area.

After my earlier miscounting I'd better check
carefully :-0 but if this is labelled B1 (and
there is another one labelled B2 on *some*
MicroVAX 3100 Model 20s) and it is three
rows of pins ... then it is a synchronous
communications connector. The same
connector was used on several other
synch comms options (DEMSA, DECnis,
DSV11, DSB32, DMB32 and DSF32).
The interface presented (X.21, V.35,
RS422, RS423) was determined by the
stub cable you plugged in.

I'll agree it, sincerely. My doubts are, mainly:
* Can I connect the hub directly to 220 volts AC ?
It appears possible if I've read correctly the AC connector info.
* How must I connect the RG58 cables ? Must I put a Ethetnet 'T'
with a terminator in the computer BNC connector or not ?
* Finally, the link connectors and you suggestion about the link
to one managed hub.
Thanks and Greetings

I'm interested in a similar thing in the Tampa Bay area, if there's
anyone around...

Yup, it's sequentially accessed. At least one company still sells &
supports it, though I don't know if they're actually producing it at
this point.. It's a really neat technology. It moves the magnetic
domains around "tracks" in (if memory serves) a crystalline garnet
substrate. These domains can be set to "0" or "1" and are read by
moving them past a detector.

Hm, we must've used different paper. Or perhaps laser printers with
different toner.
