Yes, Cromemco was the company, Cromix their unix
like OS.
IIRC, in 1981-83 timeframe someone I worked with had mentioned
he used to work at Cromemco and that they had a unix like OS
called Cromix. Cromemco were in Mountain View so likely they
were at the WCCF.
Even though z80 could only address 64k, their system had a
bank select under s/w control & upto 512K of RAM could be
added. Z80 didn't have a supervisor mode but still, the bank
select must have afforded enouh protection from bad pointers
crashing random processes.

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