Take a look at the IBM tech reference manual as one of them (don't recall
which one, XT?) does has schematics for theirs. Also as far as trying to
repair them, the common failures I have found are the switching transistors
going bad and the 10w or so power resistor opening up. The rest I haven't
taken the time to fix :).
