Does a 9000 need 3-phase power?
I did not know there were VAX vector instructions. I wonder if GCC knows about them (for
the VAX back end). It has really extensive vector support, so if the back end handles
that you'd end up with vectors probably for any language GCC knows about -- or
minimally for C and C++ as well as FORTRAN.

Wow, that Alpha number is amazing. Funny that
the VAX 780 was half the speed of an 11/83. Did the 780 have an optional separate FPP? I
forget. I wonder what an Aridus (VAX 9000) would produce.
Yes, the FP780.
We at LSSM have a 9000 in the warehouse. I doubt we will try to get it running, but you
never know.
One interesting thing about the 9000 is that it's one of only two implementations of
the VAXvector that I'm aware of. We have the other, which is an add-in board for a
VAX-6400. I got that up and running about two years ago; it's a great deal of fun,
but only for FORTRAN.
