[QUOTE="Vipersan, post: 1025623, member: 325666"] Managed to get another C64 working over the bank holiday weekend .. A guy on my TV repair forum generously donated some used harvested MOS chips he had lying in a drawer. Such chips are extremly difficult to get hold of these days. It had a blown PLA chip ..damaged cpu ..faulty CIA chip ..and the trickiest of all to pin down.. a faulty ram chip.. I suspect this pcb has been subjected to catastrophic power supply failure before being sent to the bin. On the plus side the PCB is now 90% fitted with IC bases .. If anyone has broken Commodore computers .. please dont just throw them away .. I'm always interested in dead pcbs for chip harvesting.. rgds VS [/QUOTE]
