Still looking for: Nova 800/1200 power supplies

Hi all -- Nearly two years back I picked up some Nova 800/1200 gear, mostly in pieces. I've been trying to track down power supplies for these for awhile, thought I'd try asking here again and see if I have any better luck this time :). Both chassis are the "Jumbo" variety, and take two power supplies each -- one that provides +/-5 and +/-15 and another that just supplies dual +5. At the moment I have just one power supply -- a dual +5 supply. I also only have one of the "DGC NOVA RESISTOR BD" boards that are the go-betweens between the backplane and the power supply -- the 52-pin edge connector from the supply plugs into this board, and the board plugs into the backplane. I need at least one more of these... It's relatively unlikely, but if anyone happens to have any 800/1200 power supplies going spare, in any condition, drop me a line. Thanks again, Josh
