Greetings,
I am looking for recommendations based on real experience
regarding VME-based 68020 boards which are to be
used in a multiprocessor system.  Further, since I havd
been told that the choice of backplane can make as much
difference as the cpu choice, please include that in
in your comments. As for how many is "multi" - a minimum
of three to say at most six (that is now many I can forsee
getting funding to buy!!).

Further, recommendations for VME/SCSI controllers is
also welcomed.  I view SCSI controllers the same way
I view Ethernet controllers - they should be simple but
very fast.  They should be just smart enough to do
full duplex DMA, but in general, should NOT have
a CPU on board to slow things down.
