Note that some 64s, at least, have the disk drive reset isolated from the
computer reset by virtue of a spare 7407 that was hanging around. Fiddling
with disk drive reset on such computers is futile (unless it's your drives
that need re-setting!).

Me, what I did was take one of those 19c pushbutton switches, solder a couple
of wires to it with microclips on the end, and then whenever I'm forced to use
someone else's computer, I take my reset with me! Since some schematics are in
the back of the Programmer's Reference (and are generally accurate, except for
the video output section which has been very much changed), it's fairly easy
to find a ground and a reset line. Note that it really would be best to put a
couple of clamping diodes near your switch, to avoid inductive kick. But I
doubt that those little Rat Shack switches have enuf metal in them to function
as an inductor :-). At least, I've never had a problem.
