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, - Josh
