If you need more numbers and a little more data, my

Very nice. Thanks for gathering all that info into one document.
It reminds me that I need to check the part numbers in my "Tri-Node" -
a CompuServe-built cabinet with *three* independent 9-slot DEC Qbus
backplanes, three PSUs, three boot switches, etc. I got it at the
curb (totally gutted) about 6 years ago when someone was cleaning out
a rack at the Hilliard Data Center that started out as the replacement
CompuServe headquarters but became a WorldCom facility after the
split. I was contemplating loading it up with three KDF11 boards
(since I have those already) and running three different OSes on it
simultaneously - RT-11 on one for sure, possibly 2BSD on another, and
TBD on the third. I could drop RSX-11 on the last, but ISTR RSX-11 is
rather poky on an F-11 (not that RSTS is fast on a small machine).
