The micro which most closly approaches the Multics model is the
INTEL 960XA which was used in the BiiN architecture.

Unfortunately the 386 and 486 do not feature a page table for every
segment, even though they do have rings of protection.  Further if I understand
correctly, they do not have protection at the segment level but rather
at the page level.  These facts would make the "simulation" of multics
difficult.
