	*	The 68451 may work now.  After trying three
		separate samples during the first year Motorola
		tried to push them, we did not find one that
		ran within reasonable temperature specs, let
		along the published spec.  Our software people
		got disgusted well before Motorola final sold
		us a running sample.  Even within the spec,
		the chip's translation time can easily be
		improved on by LSI, take the SUN MMU for instance.

	*	Everyone's definition of an MMU is slightly
		different, but the large number of XENIX systems
		happily running on the 8088 suggest that their
		scheme provides the basics for a UNIX system.
		Try opening your mind to something beyond Motorola
		hype.

	*	I wouldn't stoop to the level of character assasination
		to support a point.
