The 286 had protected mode.
The thing that was exciting about the 386 from the point of view of those
interested in Unix was that it had a paging MMU. The 286 was purely
segmented. I was in the group at ISC that ported System V Release 4 from
the 3B2 to the 286 for AT&T, and that lack of paging was by far the most
difficult aspect of that port. It was quite a relief when AT&T realized
that no one cared about running SysVR4 on the 286, and I got to switch over
to working on the 386.
(My relief was not complete, though, as the first thing I got assigned to
was an emulator to run older 286 Unix binaries on the 386, and after that
another emulator to run 286 Xenix binaries. I just couldn't seem to escape
the 286! :-))
