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!
I have an original documentation binder that I'll check out and
photocopy
if it has the schematics.
I do too, someplace. It's hiding though. I don't recall if it
includes that
information or not. If you end up making that info available in
electronic
form, I'd be interested in having a copy as well.
And while we're on the subject of Imsai, does anybody have part
numbers handy
for those switches? I have several that are broken to replace.
They are made by C & K. The 2-position ones are P/N 7101 and the
momentary are P/N 7105. You can order them from
www.IMSAI.net for
between $11.00 and 12.00 a piece.
That's anywhere from $3-5 more than Digikey and they are an expensive
source! I usually get them for under $7 in unit lots.
NOTE: the suffix for those switches is important as they come in
differnt mountings and with differing solder posts.
