This might be a bit of an odd question, but can anyone point me in the
right direction to find info on theory of operation of a front panel? I
have a z80 based computer which I built a few years ago (wire-wrapped)
which uses an eprom for program storage. I would like to add a front
panel (switches and lights) to it to get better aquainted with the old way
of doing things. Unfortunatly, my knowledge of microprocessor-based
systems post-dates the era of front panels. The eventual goal is to build
a hands-on display to show how systems were bootstrapped. (without
letting people abuse a 'priceless' altair or imsai)
Thanks,
