> Jorway Model 411 CAMAC?  Looks like a Massbus cable going into it.

CAMAC = Computer Assisted Measurement And Control (or something similar). 
It's a bust standard used particulalry for particle physics instrumentation.

The unit you have is probably a controller. The cable is unlikely to be
Massbus, it might well be the Unibus signals, though. You put that module
at one end of a CAMAC crate (the backplane is not just pin-pin wired, 
BTW), and put other CAMAC modules in the remaining slots.

FWIW, the single DEC serial cards (DL11) for Unibus machines used 40 pin 
Bergs for the interface cable connector. My first guess, if this is a 
quad serial card, is that the connectors on that board have the same pinout.
