The drive moter speed sometimes slows down to the point the system gets either read errors, seek errrors or just won't boot. After a while the problem goes away for a while, but always returns. Anyone have any info on the speed control board? There is not much on the speed controll PWB, with a schematic I think I could locate the problem. There is no info on this in the DEC Technical Documentation for the RB100 ----------------------------------------------------------------
