Virtual memory is not, to my mind, either necessary or
sufficient for a
machine to be a 32-bitter. Indeed, IIRC the 68020 does not have any
kind of MMU; when present, that's separate (common, but separate and
not necessary). I think the '040 was the first 68k-series CPU to have
an on-chip MMU (and if I'm wrong I'm sure someone will correct me!).
Actually, the '030 was the first one.
