The color??? ;-)
Just kidding. IIRC, the white paks are 26-3124, and have a soldered-on ASIC
which can't be upgraded without external circuitry - someone somewhere on
the 'net had a howto on adding a dead-bug 74LS10 to the newer packs to make
them CoCo3 compatible.
The older packs used a (socketted?) PAL for address decoding, and with the
datafile to program a new PAL/GAL it's a drop-in replacement.

There's multiple varieties of what you describe, it uses stackable modules.
Was also a rackmount version too. It ran a motorola version of Sys/V, at
least the ones I know about did... Also was VME, at least the CPU etc was...
for sure existed as both 88k and 68k, I can borrow my friend's motorola
product catalog for more info if desired...

Ohhhhhhh nooooo. I was writing to say that you have to go see
the Cabaret Mechanical Theatre -- Museum of Automata
(http://www.cabaret.co.uk) but the "About" page says it's now
closed for restoration for a year. Never mind.

Hey, I've got a DCA controller here in front of me. It's a full-length
8-bit ISA/MCA flippy card, with 1 BNC & 1 RJ-11 (4P4C) ports on it. One
sticker says `*LA 0006E1*' and one says `003581 REV.A' A little googling
indicates this might be some sort of 3270 controller, but I couldn't find
anything to confirm this. Anyone know what it is/want it?

Doesn't sound like you've looked at many recent Suns. The Ultra5 and later
are built like cheap PCs. Not at all like the older ones.

I've not had much trouble with them. I have three of my own, and was
responsible for "tidying up", reconfiguring, and reselling several dozen at
work. I admit the Nidex PSUs have a bad reputation, but I've only had two
(or maybe three) fail out of nearly 100 machines. You do know that a few
of the later graphics boards need 005, 008 or 010 PROMs? Same applies to
certain CPUs (the R5K needs an 010, for example, and that comes with the
upgrade kit).

I spent this afternoon splitting an Origin 2000 apart to sell part of it
off :-(

In the UK, in 2000, they wouldn't ship a power supply without an
attendant engineer to perform the complex task of undoing the thumbscrews.
(With the attendant cost, as well - of course...)
Whether this was global policy or just a local thing, or just SGI being
bloody minded for the sake of it I wouldn't like to comment :-).
Of course, when said engineer did come round, he cheered me up
immensely with "Oh, yes, this model of PSU was known to be bad, they
always blow; the replacement should be fine." Well great, thanks
for telling me when I needed to know...
I also forgot to mention the sheer awfulness of IRIX in my previous
list of gripes... Anyone else had to deal with a corrupt XFS filesystem
on a production machine? "Excuse me, my XFS filesystem is corrupt and
I need it fixed," "well, XFS can't get corrupted so we don't have any
tools to repair it." "OK, lets pretend XFS isn't corrupt but that IRIX
panics every time it reads a particular directory entry, how do I repair
it?" "Sorry, XFS cannot be corrupt, so there is no way to repair it..."
Cue a long night of restoring from backups :-(.
Fortunately for Sun, there ain't any SGI systems still in production
use round my end of the world any more...
Cheers,
Tim.
