I checked the digital 5V supply, looks okay. > Wondering if either CPU, RAM, or ROM is going corrupt... Does the DC OK signal turn off? If you have the original PS that has the DC OK adjustment, then it may simply be a matter of turning that trimmer a little. The only digital parts I'd worry about are the EPROMs, because after 30 years some of the 0's could have leaked down close to the 1 level. The solution to that is erase them and reprogram them. -- Ciao, Paul D. DeRocco Paul mailto:pderocco@...
