I thought about that, but it is my understanding (which surely could
be wrong) that multics is based on dynamicly allocated, variable size
segments of potentially large size.  Certainly, the 80286 doesn't fit
this criteria with its fixed size, 64K segments.  Also, doesn't
Multics use more than 4 rings of protection? 

Gates are a different story...a really good feature of the 80286.

The 80386 *IS*, however, Multics-on-a-chip...
