AMIX (Amiga UNIX) uses 68020+68851 or 68030 with MMU. Also WHDLoad can use MMU partially. (You know that there was 68451 MMU for 68000/010, but it was rarely used.)

There are 2 cpScc (cp = coprocessor) instructions: PScc (68851) and FScc (FPU; native on 68881, 68882 and 68040; software emulated on 68060 - in 68060.library on Amiga).
