I finally put up pics:

and got around to powering it up to see what would happen. I saw an
amber power light, a quick blink on the green "run" light, the fans
work, and the hard disk spins up, but I didn't see any output on the
serial port which I thought should've been the console. Supposed to
be a 68k-based Unix box. Apparently these were known for graphics,
but I don't see anything looking like video output (other than a
coverplate with video signals labeled) so maybe that's missing from
this one.
Manuals, disks and a tape will be included.
Anyway... if anyone wants it, it's free for pickup in Phoenix, AZ, and
if not, it's going to get scrapped pretty soon. My wife's been
nagging me to get it off the patio (clean, dry patio, out of the
weather) for years, and now there is a good chance we might be moving.
