     Without memory management things are bad on a M68000.  You get to
swap for every process switch, unless all the processes are linked into
the proper places at load time by some kludge.  The Chromatics, a very early
UNIX system, ran IDRIS, a very early M68000 UNIX port, in this way.  Miserable.
Sadly, an 8088 with no MMU is in some ways easier to deal with than a M68000
with no MMU.
