Anyone recognize this bus/form factor?

[Mike Stein]

Found a few more boards; I guess the displays, 
optocouplers and surge suppressors suggest an 
industrial system of some sort, perhaps custom or 
limited production.

Wonder why that type of connector wasn't used more 
often for a bus instead of presumably more 
expensive edge connectors; I think I do have some 
(CDC?) boards that are the opposite, i.e. pins 
plugging into sockets on the backplane.
