He didn't say that OS-9000 won't work on the MC, we just haven't done a port
yet.  Since the MC uses different hardware than the ISA, different drivers
are required.  Also, there is some difference in the way interrupts and
bus arbitration work which affects the drivers.  The hardware is currently
expensive and not as widely used as the ISA.  We'll do the port when sufficient
demand for such exists.
