I have a memory of having seen a Zilog Z-80 (not Z8002

I recall asking the people in the booth how they managed without an
MMU, and don't recall their answer. I do remember thinking that since
Unix had "grown up" with MMUs to stomp on obvious pointer mistakes, the
software ought to be relatively well-behaved ... you know: not trying
to play "core war" with itself?
I searched the TUHS archives cursorily with Google to see if this has
been previously mentioned, but pretty much all Z80 CPU references have
for its use in "smart" I/O devices back in the day.
Does anyone else remember this Z80 Unix and who did it? Or maybe that
it was a clone of some kind ... ?
looking for a little history,
Erik Fair
