I have some cables that might be interesting to CCers:
Tek ERGO cable (X-term cable with keyboard/mouse plugs on it and 3BNC)
DECstation/VAXstation/[?VAX3100?] SCSI -> Cent50 cable
IBM PS/2 (narrow) SCSI terminator (micro-ribbon?)
Looking for DSSI ((?)VAX 4000 series -> HSD50) cable and HSD50
(microribbon) terminator
smallish DG AViiON (Moto 88k) (one of the desktops or smaller tower
models)
No, I don't expect to trade a cable for an AViiON, but I will do
partial trades or just take the free advertising (same goes for the
DSSI stuff)

I got a call tonight and picked up an Eagle IIe computer, Lisa 2 (3 1/2"
drive), Vic 20, Bunker Ramo micro/mini with the possibility of picking
up a couple of Polymorphic Toasters (the orange S-100 machine.) I will
be picking up two more Bunker Ramo computers on Monday.
These Bunker Ramo computers were apparently used in a brokerage house
and the possibility exists that he has the docs for them. I don't have a
model number right now, but is anyone familiar with Bunker-Ramo and the
computers they made?

I knew it was something like that!
I have been looking for a Burroughs B1000 machine for maybe seven
years. I missed a local one that went into surplus about a year after
started collecting. I heard of another one in Ohio that I think a
museum got. (The museum queried me to see if I had found one.) Other
than that, I haven't heard of any.
I have a bunch of Burroughs B20 workstations that I bought a couple of
years ago, mostly to save from the scrap heap. Haven't been able to
find any more or any software for them. (Someone is Colorado offered to
send me some software, then disappeared, so, obviously, it is a conspiracy.)
I also collect Sun shoebox systems (IPCs, IPXs, Classics). Since I work
for Sun, I will make sure that I have software and documentation on
those systems.

Hmm. I don't have any printer generated drawings, true. Not sure I'd want
to. The normal drawings are pretty big, and lots of paper. They contain
every wrire, every pin, and every connection. Also photographic layouts of
PCBs. There are also flow charts and timing diagrams in there.
In the service and maintenance manuals you have more descriptions,
including scope shots and other kind of service information. Lots of
trobule shooting information as well.
So I still can't see what more documentation there could exist.
But I admit that I don't have any experience of IBM hardware. I just can't
imagine what more information there could be than what I have. And that
was what was delivered with the machine.

I'm in search of a couple of blank 82S123s for my recently-aquired
SuperElf boards. Who still carries such things?
Googling on 'blank 82s123' did not turn up anything promising.
Thanks,

Hi!
I am searching for the layout of an old Altair 8800 home computer.
A friend of mine is reading Steven Levys "Hackers" and is fascinated
about the Altair 880 homebrew computer.
I searched the net with google about this computer but i cannot find
sth. useful.
Anyone here with infos about the Altair 8800?

I recently bought an Altair 680 case on eBay, and am planning on trying to build some kind of 6800-based board to go in it. I'd like the front panel to be authentic-looking, and have been digging through my old Byte magazines and some web sites to try to figure out the switches they used. I've seen mostly bat-handled mini-toggles, but a few pictures have shown flattened bat-handles. I would also need to know the switch configuration (i.e. double-throw, single-throw, momentary, etc.) for the various switches. It seems like there's a lot less info around on the 680 than there is on the 8800, although I did find a pretty good article about the "new" Altair 680 in one of my "Best of Byte" volumes. Can anybody supply some switch info? Dimensions would be good; manufacturer and part number might be better.
I wasn't really planning on building a 680, but I did my usual semi-annual search of eBay for the keyword "Altair" and there was this pretty (but empty) 680 case, and in a classic illustration of Pavlovian response, I clicked "bid"...
