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.
