processor interchanging

[jnordness]

From the research I have done, the 040 and the 060 seem to be the same with the exception of the voltage regulator. (5v for the 040 and 3.3v for the 060) Will an 060 fit into an 040 socket assuming I change out the voltage regulator, if at all possible? Also, I have noticed that EC versions of processors don't have an MMU. Does the lack of an MMU seriously hurt performance? Thanks in advance!

I see those Fusion Forty accelerator cards a lot, so I was seeing about upgrading that. And the reason I was asking about the MMU is because the EC version of the 060 has no FPU or MMU, and the Fusion Forty has a socket for the FPU. The EC versions of the chip are cheaper. Thanks for your help guys.
