Hi Dick,
Well, there's a few things which are standing in my way....
1) I'm a complete newbie to microprocessor designs & troubleshooting
(although I intend to rectify that, and have bought some books on the
subject. Maybe I'll get into embedded systems using Z80s or similar...
2) I lack the tools to diagnose faults, again rectifiable from a nearby
electronics store
3) Although I don't have an EPROM burner, I can get one. Learning to use it
might be something of a challenge, but I'm sure I'll get there...
Other than that, yes - it's just a case of getting a 6502... Interestingly,
both of the versions that are currently available have extra
instructions... I don't suppose that will affect the operation of existing
CBM software, but it'd be a bit of a bummer if i wrote some m/c which
worked in one machine and not another...!
As for the offer - hold on for now, I may just bid on the German 8032SK,
and fix this the easy way. But I definitely seem to have been bitten by the
"DIY" bug.... time to subscribe to that home-made computer news group, I
think...
Cheers!
Ade.
