So essentially duplicating the most-often-used functions of a Fluke 9010A
with a 6502 pod, but much easier to build/acquire.  That would be a handy
little device.  Any number of microcontrollers would either have enough
native I/O for 24 bits of address+data plus bus control lines, or could
inexpensively add counters or shift registers or I2C I/O expanders, etc.

Neat idea.
