Can't help you here - my 660 has leads marked with red, green, and blue..

The two 68000 sit there pretending to be a 68010 - I believe one does the 
work, and the other pretends it's a MMU - but I may be wrong.  I can't see
replacing them with 68010s being any use.

The best way to improve performance would be to get hold of the processor
(2 boards) & boot processor (1 board) out of a 660 - people *must* be
throwing them away by now... - then you'll have a *real* computer (68020
look-alike).
