Question relating to the two I/O processors in the Mac IIfx:

>Question: Exactly what type of processors are these and what are they doing?

I believe these are 6502's used as a core in a chip that has RAM/ROM/etc..
making them single chip I/O processors.  I believe the 6502's run at a
fairly high clock rate (10 Mhz comes to mind) which would make them
fairly powerful I/O processors indeed.
