Summary: Can we have some benchmarks for the 1980s? (It's almost 1990!)

Is anyone besides me bothered by the choice of machines used in
this comparison?

Note that the 11/780 is a mid-1970's design using mid-1970's
technology (they were already being produced in '79 I believe).

I think (I'm not so sure on this one) that the Amdahl 470 V/7 is
also one of Amdahl's earliest machines.  (Does anybody know the
vintage of the FPS 20/64?  Is it modern?)

I'd like to see benchmarks against some modern-day VAXes, e.g.,
the VAX 8800, and against some modern-day big mainframes, e.g.,
IBM 3090-class machines.  Then, we might get some idea of how
little machines like the MIPS and SUN fare against current big
timesharing systems.  (My guess is that the benchmark will run in
under 30 seconds on a 3090, and that the big VAXes will beat the
MIPS/1000...)

Also, notably absent is the figure for the MicroVAX II running
VMS (which is what it was intended to run).  What is the
"fortrel" compiler?
