AT&T 3B1 Unix PC

[Eric J Korpela]

I have one as well.  I think mine has the 7300 stamp rather than the UnixPC
name.  It's got the 8086 coprocessor board to run DOS apps.

I have the dev kit, a few OS revs, and a pile of documentation.

For it's time it was a pretty decent low-end workstation with a fairly good
(non-X11) windowing system.  Biggest problem was how slow it was at floating
point, probably due to a crappy math library.  I don't even think there was
an option for a 68881.

Since it was designed by convergent, the machine itself it a lot like the
Convergent Miniframe (possibly even software compatible). The unix itself
was pretty good with virtual memory and memory mapped files, but the max
per-process address space was a 2MB which was also the max-RAM supported,
IIRC.
