A minicomputer interface for realtime operations: an application to operant conditioning

A PDP-12 interface was designed, constructed, and tested for realtime input and output of binary information. Within limits this interface can be used with any peripheral device which operates in the binary mode. In addition to its generality of application the interface features include ease of expansion and low cost. A description of its design and operation is give here in terms of a typical application: the control of behavioral equipment (i.e. “Skinner Boxes”) for operant conditioning.
