I'm trying to help someone identify a pair of plug-in modules:
Additional photos here: http://www.vintage-computer.com/vcforum/album.php?albumid=219
They're definitely from a Burroughs system; if you look carefully, you can see the "B" logo on the upper plate (right-hand side). They seem very similar to this flip-flop module from a B250:

However, I've seen photos of similar modules from other systems such as the B5000.
I realize that the photos I have may be inadequate for identification purposes, but maybe somebody in this forum can shed some light on their most likely source. Sadly, I have never met any of these old Burroughs systems in person, so the details of their components are unfamiliar to me. (Actually, I would love to find schematics for some of these modules.)
BTW, if anybody here collects this sort of thing, I know that the current owner would like to sell them.
Another question, slightly OT: The same person has sent me photos of a number of boards from various sources (UNIVAC, a Datapoint terminal, and some mystery NCR machine). Would I be violating etiquette if I posted them somewhere at VCF to ask for help in identifying them?
