  Some of them are downright zippy.   I'll have a VAX 7000 and a
4000-700a on HECnet soon!   Zoom!

Dave: Nice. What's the 4000-700a pull VUP wise?

  40 VUPs.

I was *VERY* shocked
going from a 4000-m300 "Pele" at 8VUPS to the 4000-m90A at 38VUPS. It's
like greased lightening by comparison.

  Oh yes, I'll bet!   And keep in mind it's not just the CPU speed but
the memory bandwidth.   It really sped up during that era.

Sadly, no VPU though.

  I WANT WANT WANT a 6000-500 with a vector board.   It's a shame that
VAX 6000s have dried up so quickly.   I must've passed up thirty of them
over the past fifteen years.   I'm getting a 6300 next month from a
semi-local guy.   That'll be nice, but no vector boards for that model.
