[Simh] What is the best machine to run simh?

[Rick Campbell]

SRI also has an ALPHA version of this tool.  It is called PT_ALPHA.EXE.

Instead of vesting the VAX version just run the AXP version.

Don't you think maybe something is wrong in the test procedure when
every result in the Dhrystone column is 666666?  I would look for some
kind of significance underflow.  Like too short a run time to
accumulate enough timer ticks.

For that matter, every result in the MIPs column is either 1000/8 or 1000/9.
