RE: the discussion of running an '040 board on a 25MHz vs. a 16MHz A3000.
 
I thought the whole idea of having the Fast Slot in the A3000 was that
you could add co-processor boards like an '040 board, and they would use
the motherboard's RAM and bus.  Thereby making it cheap relative to an
A2000 co-pro. board that would need its own RAM, bus, and SCSI host.
 
SO,  the realistic speed limit for an '040 board in an A3000 sounds like
25MHz, since going any faster means you wouldn't be able to use the
motherboard's resources.  And likewise, if you have a 16MHz A3000, then
16Mhz would be the limit.
 
Not that you *couldn't* go faster, just that the card would be more
expensive as it would need its own RAM, etc...
 
Am I right?
