The 11/45 has a row of little step-down regulator modules,
all plugged in with
those horrible AMP Mate-n-Lock connectors. We often had bad
those and they would sometimes burn the connector housings
or char the
ends of the wires. That was all about 1980, I can't imagine
with age. I think you may have more trouble with these than
in the machine.
You will probably also have problems with all the fans. I
replaced the lights in
our console with LEDs.
As for a dead console, if the ACOK signal is indicating "not
ok" then the console
probably will be frozen.
