Diablo 3000 schematics wanted

I suspect the answer is no, but before I spend a few afternoons tracing out the diagrams, does anyone have a schematic or (real) service manual for the Diablo/Xerox 3000 computer, in particular the MRPRO CPU board. This is a 1980s all-in-one business desktop computer with 2 internal 8" drives. Based on an 8085 CPU. I have one that was mangled in the house-move (the movers decided to cut the keyboard cable for me). I have now repaired that (and the signals do make sense) but I have other faults (these were probably there before the move, I had not run it for many years). Power lines are fine, CPU chip is getting a clock, but the ready pin is held low. So not a lot happening.... The CPU board is not complicated, really (about 50 ICs, all of them standard) so it is going to be possible for me to trace the schematic if that's what is needed... -tony
