An interface for controlling external devices via the IBM PC/XT/AT parallel port

This article describes the construction and operation of a simple interface to control external devices via the IBM PC/XT/AT’s parallel printer port. The interface is relatively inexpensive and easy to build. It is potentially useful for controlling behavioral experiments.
