I'm not sure that you'd gain much over traditional diagnostic exercises,
though. Reseat chips, pull anything not needed to get the machine to start,
test PSU & connections, swap RAM banks, check clock and reset lines etc. and
it's usually possible to narrow things down far enough to do some more
detailed fault-finding.
I got a PET and FIT, thinking they might be useful, and I've never even used
them. I think I have the schematics here with me somewhere, should you want to
try building them :-)
