For some months we had a gremlin here; sometimes, not too often,
when accessing files longer than 16K on CP/M, the system would
simply get lost and wander back to the monitor.
	Larry Niven and I have identical systems.
	Tony Pietsch simply swapped Z-80 chips between my
machine and Larry's.  Both have worked perfectly ever since, a
matter of about 3.5 years since we opened the cabinets last.
	Thus I believe that your problem went away when you
swapped chips...
