Northstar CPU Card in Regular S100 Bus?

That should certainly be the case with the N* CPU I recently gave to one of
the list participants. It had no hardware on board which would prevent it
from working with pretty much any other S-100 hardware, aside from the usual
risk, since there were no real standards, even after the adoption of the
IEEE P696 standard. With more signals than were needed, it was always
possible another maker's card might expect different combinations of signals
to do the same job.
