As far as I understood
the docs the B012 is just a TRAM carrier with
some C004 link switch chips. It is VME form factor, but the pinout of
the connector is very non-VME. I think it was build that way so that
you can use a generic VME card cage and you had to provide your own
backplane.
The (damaged) card cage I pulled the boards from supports this. It
hadn't a real backplane at all. Only connectors with some hand soldered
wires, mostly for power. There where cables hanging out where the host
was connected.
