I have found a manual from Video Monitors Inc (VMI) that I have written
''PERQ 1 monitor' on the outside cover of, so I assume that's the one.

The circuit diagrams are not very clear (it's an nth generation copy I
am afraid) but there are theory-of-operation and troubleshooting
sections that might be useful to you.

Would you like me to get it scanned sometime soon?
