I have the full list available from DSN, but it isn't complete. I can't post
it here, though, due to it being copyrighted, but I can post VUPs for requested
systems from the list, if you ask.

The numbers above are the VUPs. The DSN listing for the /90 and /90A are off
by 10. I got ambitious and ran some more tests. The /90 is 32-33 and the
/90A is 38-39. The VAX 7730 systems at work are 150 VUPs.

What's interesting when reviewing the list is to see how the bus architecture
impacts the VUPs on identical CPUs. For instance the 7610 is 35 VUPs but the
6610 is only 32 VUPs.
