MicroVax-II Ultrix-32m combo benchmarks

[Douglas Robinson]

Now that DEC has announced the MicroVax-II I thought that the net would
like to see some benchmarks...  You will need a 132 column printer for
this (or a dense printing mode).  The source to the benchmarks is
available on request (PURE computational benchmarks - meant to run CORE
resident on LSI-11 running VENIX-11).  Please note the machine
configurations at the end - they are important for comparing floating
point results (FPA or NO FPA makes one hell of a difference!).
