Bare in mind the keyboard keys will likely have to be re-foamed. I had to
do that with my Visual 1050, which is the full system version CP/M
computer. I'd see if there are similarities to the 1050, I bet the video
display circuits would have similarities, you might be able to find 1050
schematics if you can't find exactly what you have.

After some basic repairs to the power supply section, I now have a
flashing "ON" light on the keyboard which I believe is an error code from
the self test (taking queues from the Visual 100 manual).
CPU removed - "ON" light stays lit
CPU installed - cold start - 3 beeps, then ON light flashes
CPU installed - less than 5 minutes since last power up - ON light
flashes, no beeps
Messing with the Mask ROM in it's socket also created a few scenarios with
lots of fast beeps, and the CAPS LOCK key staying lit, but I reseated it
and the system returned to the above situation.
CRT section doesn't appear to start up, but didn't blow up either, so
that's a plus. Have not had a chance to go over it with a scope yet.
So if anyone has...
- parts list
- user guide
- circuit diagram
- a spare logic board laying around
- or remembers anything about these terminals
Please let me know!
Cheers,

myself. It's for a VT100 clone terminal
called the Visual 100 - from
around
1982.
Mistake on my behalf. Was working on it last night and it's actually the
