Besides a huge box of manuals that I've sent to Al, I found
five BBN
computers and I'm attempting to rescue enough of one to make a workable
system for Tom Uban. Plus all the cards out of the other ones for him for
spares. The BBN chassis is just too big to deal with but I got ALL the
cables, the complete PSU (on the back panel!), the multibus card cage (and
all the MB cards) and the switch card that lets all the CPUs talk to all
the other CPUs. The BBN CPUs are odd in that they don't plug into a socket
so the card cage isn't absolutely necessary. All the power and signals go
through connectors on the front of the card. Warning: this is a SCRAP
place and some of it isn't pretty!

I designed the Multibus backplane in that BBN machine about 20 years ago.

Mupac would make sense. I am pretty sure that was the brand which we used
at BBN when we built the Butterfly machines. I used to have a large VME
chassis made by Mupac that I picked up from BBN while I was there. We used
the VME interface on the GP1000 followup, the TC2000.
