Agreed, sorry, didn't mean to sound like I didn't.  If anyone is likely to know where to find them it would be the 68kmla folks (or, in the past, mac68k.info forums, but that place doesn't seem very active anymore).

Even so, those PSU schematics tend to be thin on the ground, and the IIcx/IIci/Q700 supply is especially annoying to retrofit anything to because of its weird "drop-in" Mini-Fit socket.  I personally wouldn't mind just replacing the guts of one with something modern and splicing a panel mount one on, though.
