It's in storage right now, I don't have a scanner set up at the moment, and I can't remember off-hand whether it has /12 schematics, but it's monstrous and has lots of schematic foldouts. I'll see if I can find it this weekend and let you know about the latter. I would think, though, that the PSU is covered. The A13 chassis was used in other 990's. I have a /10 setup in one. Been decades since it was powered up, though. later, jbdigriz
