Actually, the 68010 does NOT have a built-in MMU. The Sun2 has a Sun
MMU implemented in discrete logic on the mainboard. It's basically an
earlier version of the Sun3 MMU (which itself is an earlier version of
the Sun4 MMU :-)
Presumably, the 310 has an HP MMU, like the 320 does, or maybe it uses
that really old Motorola MMU (the one before the 68851).
