   Well, MT C-shell is at the least multi-tasking, I believe it was written
with the Micro-RTX multi-tasking OS extension, which I know for a fact is
multi-tasking.  As to whether or no the C-shell is inherently multi-user,
that I don't know, but if it can multi-task, it can support another user if
you write the code.
   The 68000 has user and supervisor modes, but this has nothing to do with
multi-tasking.  Any microprocessor can multitask, just look at MP/M (a 
multi-user, multi-tasking C/PM thing).  It ran on a Z80, which didn't have
much of anything.
