that rack contains two VAX 4000/700As. 
 Ahhhh! I get jealous reading that. The 4k VAXen are quite nice and the
 700A has around 33VUPs. My best VAXen are a 4k400 and a VS4k90.   
 The VAXstation 4000/90 is a 42 VUP system and the VAX 4000/400 is a
 16 VUP system, so you aren't doing too bad.  I seem to recall the
 VAX 4000/700A is about 40 VUPs and the /705A is about 45-50 VUPs.  
   The VAX CPU Summary lists these numbers:

   VS4000/90   32.8 VUPS
   4000/700a   40 VUPS
   4000/705a   45 VUPS  
 The numbers I have are from DSN, and the 42 VUP rating for the 4000/90 feels
 right to me. 
Maybe the /90 is 32 VUPs and the /90A is 38.8, which would make sense if the
list on DSN is off for both system.  What leads me to believe the DSN listing
is in error now is I just ran a test program on a /90, 90A, /400, and /500,
and the numbers for the /90 and /90A are way off from what I'd expect if the
ratings from DSN are correct.  I'm going to run some tests this weekend to
try to get better numbers.

I wish the original DEC test program was available.
