I was referring to the separate Motorola MMU part, the 68451, which you
called "utterly ridiculous garbage".  My data sheet on it is at home, so
it is kind of hard to see what you are referring to (all I have is the
68000 User's Manual here, which has a brief summary of the MMU at the back).

What do you feel is wrong with the 68451?  (Besides the fact that, last time
I looked, it cost more than the 68000, I mean.)
