This is a BBN Butterfly system. The processors interconnect through
a "Butterfly Switch"

I have to check with the Computer Museum, but this may be the only
surviving system. It's a drag you weren't able to save at least one
of the chassis.

try googling "bbn butterfly switch"

Butterfly Switch
A parallel processing topology from BBN Advanced Computers Inc., Cambridge, MA, that mimics a crossbar and provides high-speed switching of data between nodes. It can also be used to create a hypercube topology.
