VS 3100m76 and VAX 4000-300 use the same CPU, but DEC sais the m76 has 7,6VUPs,
the 4000-300 has 8VUPs. Don't know if this is a difference in cache, or a
difference in I/O. My personal checks (compiling NetBSD kernel) resulted in
the 4000-300 being slightly slower than the VS 3100m76.

But both are very fine boxes, if you like the QBus, you really should get a
4000-300. 4000-500 port might take some while, the CPU is a bit difficult.
