AFAIK the 68000 and 68010 hardware interfaces are much the same, the big difference between the 2 processors is what is saved on an exception (as we have been discussing here). And there is no reason why that would affect an MMU. The 68451 is not a common chip, though. Most people using the 68000/68010 did indeed make their own MMUs. The machine I think of for the 68451 is the Torch XXX which puts it alongside a 68010 (and a 68450 DMA chip). -tony
