Hi,
Yes, but I would have thought that the main problem is
that
you're effectively shorting an output....
Actually, I hadn't thought of that. It's a good point.
I am suprised it was the processor that failed,
though. AFAIK,
the processor in a C64 never outputs anything to the reset line.
Well, I didn't actually do the fault finding on these machines myself. But
the chap who did repair them said he'd had to replace the 6510s.
I assume that spikes from the unbuffered switches had fried the 6510s reset
circuitry...?
There's a fairly easy modification IIRC that adds
a reset switch
in parallel with a capacitor in the reset circuit....
As you say, that's the best way of doing it.
TTFN - Pete.
