Larry definitely has hit the nail on the head here.  Speed is not really the
issue here.  The issue is the cost of maintaining more than one basic kernel
because you are supporting different processors.  Even Sun has quit offering
SunOS upgrades at the 4.X level for the Sun2 line of processors, because
upgrading separate a version for the 68010-based architecture was no longer
justifiable.  Since C-A never built a 68010-based machine, there is really
no reason for it to create and maintain a separate version of Amiga UNIX for
the 68010.  As for the 68000, non-hardware assisted VM is "as slow as molasses
in January," so very few UNIX afficiondos would be willing to settle for
a 68000-based UNIX in today's market.
