UNIX started long before the 80386, though.  (Unless the PDP-11 etc 
were 386's ;)  )  I'm not sure when 1BSD and 2BSD came out, but I'm 
assuming one of them should be old enough to work.  If not, there's 
gotta at least be something else out there aside from boring old 
progman.exe that can be run on it.
