Re: MPS 6530

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?

TIA,

mike
