I keep reading about replacing a defunct 6530 with an EPROM and either a different but compatible 6530 or a 6532, but so far I haven't found any actual instructions or schematics; can anyone point me to some relevant info? I've got a couple of dead 8050s that might need one of these. On a related topic: I assume that no one has a 6530-004 TIM version, but are the ROM contents available anywhere in machine-readable form?
