Good one! I didn't see that coming. :-)

I always found it amusing that Data General's computers were
named after transitory phenomena: Nova, Supernova, Eclipse.
Of course, in the grand scale of things, we all are. :-(

All,
A few months ago, I mentioned one of my suppliers had Belden 89880 thicknet
Ethernet cable. Well, last week I finally made it down to his warehouse and
picked it up! The final bits for a test segment came in today, so I set up
a little link between my SPARCstation 10 and DEChub 90:

Anyone interested in cable can email me directly (please change the subject
line, it'll get binned into my cctalk folder otherwise). I can provide any
level of "kit" from just the cable to fully ready to go. I do have a very
few NOS Cabletron ST-500-01 transceiver/non-intrusive tap kits as well.
Thanks,
Jonathan

I have bought from this seller before (very happy with the results), but am
not otherwise affiliated.
The -11/04 is a nice UNIBUS starter/test machine (my UNIBUS board debug
machine is an -11/04). The CPU is a single (hex) board, and it's really simple
and straightforward - very easy to work on and fix. (You don't even need to
put it on an extender card! :-)
Depending on the backplane that's in the machine, it might be super-easy to
upgrade to an -11/34 (if it's a DD11-P, as many /04's are, just pull the CPU
card and plug in a set of /34 boards).
Not sure what's up with the M105/M7821; they aren't standalone cards, but go
with some other card (they are addressing and interrupt/vector
functionality). No idea what it was, though...

Ah, the days of devices that just did what they were told without trying to be
effing rocket scientists about it!
(Yeah, yeah, I know _some_ of the things the later ones did, you had to be
close to the hardware to do them, but too often they had this 'we're from the
device manufacturer, and we're here to help you' thing going. I used to have a
photocopy of a great article in a trade rag which explained why complex devices
were a Bad Idea; maybe I can find it, if anyone's interested.)

I'd start by dumping and disassembling.
(If you need something to find out where in memory they are, I have
a register discovery program that sweeps the I/O page and lists all
locations that respond. It's probably 173xxx though, that's the
DEC-allocated spare for ROM.)

I have a couple of Simpact VME form factor DSP cards (DSP-LC) which were used in a fancy telephone answering machine for radio stations. It was part of a big system which allowed listeners to call in and get the weather, lottery, joke-of-the-day etc. They could also enter contests and record their phone number via DTMF.
