I think you've gotten a couple things mixed up...

The modular systems under discussion at the moment are collectively known
as NGEN systems. They were developed by Convergent and sold under license
by Burroughs and a few other companies.

The Convergent Mini-frame and Miti-frame systems were M68k-based UNIX
workstations and not very much at all like the NGEN systems.

The Bxx designators are Burroughs nomenclature. The Convergent-labeled
systems had different model numbers; My 8 MHz 80186 NGEN system is a
CM001/8. They all ran an OS called CTOS (or Burroughs-badged BTOS).

All of my power supply modules have the same rating (10). It's not
necessary to power every module; if you have six modules in a system which
have a power rating of, say, 36, between them, you only need four power
supply modules (collectively supplying 40 power units).

There are probably additional rules on hooking up power supplies, but I'm
not able to speak of those just at the moment.

I was able to defeat the password on a server system by connecting the
drive module to a password-less system and fiddling with a file. If that
sparks inspiration in anybody, drop me a note and I can try to dredge my
memory for specifics.
