There a re a couple of systems that used a 68000 in a Unix type environment. I
have worked on both.The first is an Altos ACS68000 system that used a 68000 and
4 (four, count'em) 68451 mmu units. The way it did the memory allocation was
to use "stack probes" to trip up a memory fault interrupt.
Thanks Al

Err, DEC sold a PDP-8/LINC hybrid themselves (interesting machine, it's
covered in one of the standard PDP-8 processor manuals), before the PDP-12
came out; the -12 was basically a re-engineered version of the 8/LINC.
