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 
contacts on
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 
they've improved
with age.  I think you may have more trouble with these than 
anything else
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.
