Well, okay, parts of one. Big parts.
For now it is in storage. Guess I have to get a basement next.
I'm not even sure exactly what I've got. It is from a Univac 9200.
Looks like a line printer and control console in one very big box,
about the size of desk, but maybe twice as tall. Switches & lights,
and discrete transistors. It was the box that had the "Univac 9200"
label on it, so maybe (hopefully) it is the CPU. When I move it
>from its current temporary home to a more permanent one, I'll get
pix & details.
There is another box that I didn't get, but may still end up with
after its winner picks a few bits out of it. Seems _he_ actually
has customers still running these things, and needs a few specific
parts. So even if I get it, it won't be complete. But I can't
complain, with those parts going to keep another Univac running.
Also got a card punch, which I got home by partially disassembling
it, to make it fit in my car. When I opened it up, I found a three
ring binder labelled "Univac Servicing Documents" - schematics,
mech drawings, all sorts of good stuff!
So, anybody know anything about 9200's? A web search didn't turn
up much. Introduced in June 1967, 8K of memory, that's about it.
Bill.

Not much at all. I spotted a few uVAX 2000's and a uVAX 3100.

I'm very familiar with them; I wrote the LCDProc driver for the B.G.Micro
"PIC-an-LCD" serial<->LCD adapter chip. From the white tent in the back
corner of the flea market, I got a box of 20x2 florescent displays for $20
(different protocol, same concept as the LCDs).
If you want to write offline about interfacing LCDs, let me know.

As has already been mentioned, Dayton is _not_ the place to go to look
for used DEC parts. I only spotted a couple of table-top uVAXen. I
did get a Kaypro 2 for $25 (and the kid dragged to my car!), a $2 VIC-20
with $1 C2N and some modern stuff.
I didn't spend anywhere near as much as I usually do. Not all that many
things lept out at me. There were scads of $5 and $10 Pentium boards,
crates of ISA NICs and lots of stuff that just isn't all that interesting.
I did make the T-shirts, one from the photo of a working PDP-8/e and one
>from the scan of the marketing literature. The text above and below the
picture said:
Wanted: PDP8's
Report all sightings to classiccmp(a)u.washington.edu
Several people walked up and started conversations based on seeing two of
us wandering around with a PDP on our backs. Nobody had any spares. :-(
P.S. - where's a good place to get a Kaypro boot disk? I have a licensed
copy of teledisk so I should be able to make them from bits, yes?

It has a label identifying it as "Adapter/Eliminator" or similar. They're
*very* rare, partly because Acorn tried to recall them, and partly because
not many were sent out before the problem was spotted. There's one fairly
common one, which *isn't* particularly prone to go "phut", and that's
probably what you have. The only thing wrong with that one is that it
doesn't have much spare capacity, and therefore has no connector for a disk
(or w.h.y.).

Yes, there were a lot of people that suggested the next upgrades should be
easier.

<11/78x was not renowned for speed. ISTR that the interface was one bit wide
The LSI-11 to vax hardware was wider I think 16bits bt the microcode was
some 60-80 bits so it took a long tome to build a few words of uCode.

Or keep a look for the gray wall (later version of similar material).
If memory serves orange was V4.XX (maybe V3 too) and gray was V5.XX.
And yes they are s significant resource. About six months back I lucked
into a copy of the gray wall (30 volumes!). Would never part with it and
it's my first set even though Microvaxen were something I was involved with
since '85!

Sun is playing mind games with you. You will know that you've reached
the bone-us level when you have in front of you a type 3 mouse with
the pins in its RJ-11 plug and a type 3 keyboard with a standard RJ-11
jack that won't accept the pins.
I have a type 2 mouse here. It's black with gray buttons, and has a
Sun sticker on top with the purple, on-its-corner Sun logo and black
"sun" text. On bottom there's a Mouse Systems label with the
following dot-matrix imprint:
MSC 900783-002/01
SN MSC BQ00226
MADE IN USA
Type 2: keyboard and mouse both have RJ-11 plugs
The 2/120 can have RJ-11 jacks for this combination; both devices get
plugged separately into the CPU cabinet (but I think the connectors go
to the bwtwo or other framebuffer).
Type 3: keyboard has RJ-11 jack for mouse and DA15 plug to system;
mouse daisy-chains through keyboard
The 2/50, 3/50, 3/60, and I guess most Sun 3s excepting the 3/80 use
this DA15 connector. The 2/50 came with an adaptor box that plugged
into the DA15 socket on the back of the CPU and brought out two RJ-11
jacks. The adaptor box works on Sun 3s too.
Type 4: keyboard has mini-DIN plug and socket(s) for mouse; mouse
daisy-chains through keyboard
There's also an adaptor box that plugs into the DA15 socket that
brings out a mini-DIN socket so you can use a Type 4 keyboard and
mouse on your Sun 3 -- I guess Sun ran out of Type 3 keyboards before
the service life ended or something. Or maybe people with Sun 3s just
wanted to use Type 4 keyboards? (Ewww, but then I don't like the Type
4 keyboard.)
Somewhere along the way (I think midstream Type 4, or maybe when the
Type 5 keyboard was introduced?) the mice changed to a high-resolution
flavor with a denser grid on the optical mouse pad. Predictably, old
and new mice and pads don't work with each other.

A friend gave me his old IBM 286 which I'd like to revive for my
wife's use. When I power on, a red light indicates the machine is
looking at the 5.25 floppy drive, then I hear two beeps, and
nothing at all appears on the screen. I'm thinking that maybe the
BIOS somehow got trashed but I don't have a clue what to do about
it. I don't think there's anything wrong with the monitor. I
think the computer just doesn't seem to know it has a hard drive
and monitor connected. Any advice would be sincerely appreciated.
I tried removing and reseating all the cards because that's
sometimes solved problems when I had my own 286, but it didn't do
any good with this machine.
Thanks in advance.

Does anyone have the jumper settings for the Tiara Arcnet LANCard AT? I
recently got one of these cards, and all of the jumpers were missing.
Does anyone know where to get drivers for this card? I've tried to find
Tiara's website, but I can't find one anywhere. The only one that may have
been it (www.tiaratech.com) doesn't seem to have an index page.

Hi all.
Through a lovely bit of serendipity, I've just been offered a PDP-11/83
that's local to me. Before I accept, can anyone help me with the following
questions:
How big is this classic likely to be? Most PDPs I've seen were
refridgerator sized, with washing machine sized disk drives, tape drives,
etc. Is that about what I can expect, or is the 11/83 one of the later,
smaller 11s?
How heavy might it be? Would it be a lifting job for 2? 4? 8?
Does it require special power? My home isn't wired for anything beyond
household current.
Any help would be much appreciated. I'd love to save this machine, but
there are limits to my space/money/housemate's patience.
Alternatively, if anyone else is in or around Calgary, AB, and would be
interested in this machine, e-mail me off list. If I decide not to take it,
I can put you in touch with the owner.
Thanks in advance.
