The XPC board is our current processor board.  It contains 2 ns32532's
running at 30mhz.

Currently from 2 - 20 processors.

On-chip the 532 has 1k data and 512 byte instruction caches.  They are
both write-through.  Externally to each 532 on the processor card is a
256k ownership-based write-back cache.

The Nanobus has always been and still is an 80ns, 100mb/sec pended bus.

Got me.  I never can find 'em :-)
