This is true *only* for the 68K Cromix. They also sold a Z80
Cromix that one could run on a System 2 with several additional
banks of memory. As one might imagine, the Z80 version was, even on
a good day, a *dog*. I think the OS stabilized at aroung release 30.

The 68K version also supported a CDOS simulator. This made
things fairly nice, since one could execute programs without regard
to what CPU (680[00,01,02] or Z80) or OS (CROMIX or CDOS) they were
intended for. The loader would figure things out, and fire up the
appropriate CPU.

All told, the Cromemcos were *not* bad products. From the start (and
they *were* at the forefront with the S-100 bus), the products were
well-engineered, and pretty solid. Save for a few incorrect
marketing decisions, they might have been a major player yet.
