The most useful debugging tool mentioned by the classic programmers was
the HP logic analyzers.  These provided all sorts of frills.  It's kinda
over my head so I'd have a hard time explaining what they do, but anybody
who is really hard-core in their programming could probably get a lot out
of use out of these things.  I believe they clipped onto the 6502 and they
could actually disassemble code on the fly and monitor all the signals
coming off the pins.
