Don't need a floppy, do need a HD <G>, but I need the negative voltages for
the A/D card I have, unfortunately.  I tried removing the negative leads to
the power supply, creating a "good power" signal, and the pc worked fine with
only the +5 +12 volt lines, however the A/D card, when inserted, wasn't even
remotely stable, even when measuring 0 to +12V only signals, such as in a
card.

Will do Dan, probably better than filling up an EFI mailing list with PC
power supply issues :)

Thansk!
