#060 MP Board
Paul,
The MP board will address any memory in the system, however, accessing the
motherboard memory will be like putting all of your programs into chip memory
now… SLOW. Having 64 bit (or 128 bit) interleaved memory connected directly
to the processor is the fastest way you can go. The Z3 Bus has a max bandwidth
of 25Mhz (on a good day with a tail wind), so accessing memory outside of the
memory on the same board (even to a 2nd MP board) will be limited to the speed
of the Z3 bus.
