Has anyone tried swapping a 68EC040 into a Mac? The Mac IIs don't have a (real) MMU and they work just fine, you just can't run Virtual Memory.

Does anybody know anything about the 68EC040? Is it a different die without MMU/FPU, or is it just the regular 68040 die with the MMU/FPU disabled? If it's the former, it might be a better choice for extreme overclocking, due to less heat production.
