Heh. The Challenge L can't take enough CPU or memory boards to suit me as
it is. The doco says you can get 8-way memory interleaving if you have four
memory boards, but the L only has room for three. On the other hand, it you
can have something like 15 or 20 SCSI busses....
I'd swap my Challenge L backplane for one with more eBUS slots and fewer VME
slots, but the Onyx backplane is the wrong direction.
