Hey everyone,
I know it exists out in the wild somewhere, but I can't find a copy
myself. It's for a VT100 clone terminal called the Visual 100 - from
around 1982.
If anyone can help me track the circuit diagram down, and/or any other
information too, I'd be very greatful.
If payment is required I have the usual PayPal etc.
Thanks!
Jono

I scanned the reference manual if you haven't found it elsewhere, has a
small amount of detail about the hardware, don't think it had a circuit
diagram though. I only have the manual, I haven't seen one for decades.

Thanks for the manual :) Much appreciated.
No diagram but lots of other useful information.

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,
Jono

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.
