Don't forget the 5400 - I can't see that any of the microVAX systems, with
the exception of something like the 3540 would be competative in terms of
performance.  Admittedly, I'm just guessing, but it's certainly worth some
consideration since the 5400 has similar I/O and expansion the the high
end microVAXEN and unless DEC botched something, the CPU performance should
make it pretty quick.
