Concurrent CP/M-80 is entirely possible and feasible, although I can't
say that anyone has actually done it (yet).  The principal is
relatively simple: take the example of a bank-switched,
interrupt-driven, multi-user system, add a small exec in the common
area, and turn it around so that you can select your current home bank
while the interrupts allow the processor to service any activities of
the other banks...
