Anyone happen to have the schematic for the original SuperBrain's power
supply / I/O board? I thought I'd found it on Bitsavers (see here:
http://bitsavers.trailing-edge.com/pdf/intertec/schematic.pdf, pages 11
and 12) but now that I've sat down to do some debugging the two don't
appear to match (the schematic is dated 1981, so it's likely describing
a later revision than the one in my machine...)
Mine's labeled:
Intertec Data Systems
(c) 1979
Power I/O Board
1424002-04
Rev. 04
Currently the +12V rail is only reading a couple of volts under load and
a schematic'd help trace down the fault. (I will get better at
debugging power supplies, I will...)
Thanks,
