Hello!
That was also a board vendor. FYI: The first GASP [GetAway Special
Program] a Space Shuttle payload made use of such a board.

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 =

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,

You may be thinking of Cromemco.
