Hi
I have an old schematic that I got from someplace but the quality
is not that good after a scan.
I though I'd pass one what I found on my panel.
The first thing I found it that the data cable was backward.
This is that cable that goes from the panel to the CPU board.
Thing will seem to work, like reset and run but any address or
data will be messed up.
The next thing I found was that one of the open collector
drivers onto the data bus was not working. These are used
to jam instructions onto the data bus when you do front panel
operations.
These are places to look for things being wrong on your machine.

Does anyone know where I can find the schematic for the IMSAI CP-A
(operators panel)? Every source I have looked at just has the
assembly and operations manual for the CP-A, but not the actual
schematic. I'm trying to bring back an old one from the grave, and
having an actual schematic would help a lot!
Thanks,
-Mardy
