Yesterday my girlfriend and I returned from a hastily-scheduled road
trip to Maryland; we went to see a friend who is gravely ill. While we
were in town, we took the opportunity to visit a few other people.
Another friend up there is preparing to move, and he dropped a few
things in my lap since I was there with a mostly-empty car.
The first was a Data General Aviion AV300 workstation. This is one of
the few machines built around the Motorola 88K CPU. It came with its
original keyboard, mouse, monitor, and a full set of DG-UX manuals. I
don't yet know if it's functional, but according to my friend it was
running a few years ago.
The second is something I'm REALLY excited about. We went to his garage
and he pointed me at two dusty card-cages full of boards, and told me
that he picked them up from a college loading dock twenty years ago, and
that he had no idea of what they were, but there were core memory boards
in them. Oh, and there's this lights-and-switches front panel that goes
with them. (!)
Upon getting them home and digging around, it appears to be a nearly
complete Microdata 1600 CPU. I have the two backplanes with card cages
and boards, and the front panel, along with some cables. I lack the
power supply, but I can build one of those...with that, I think I have
enough to resurrect the basic CPU.
Neat stuff!

I'll be really interested to see how the 1600 restoration goes. Some
pictures would be nifty - hint, hint. :-) I keep thinking I'll dig the
820 I have out of the garage some day... I never worked with a 1600,
but I sort of assume it is in at least some ways a descendant of the 800
series.
