A Microcomputer Interface for External Circuit Control.
Gorham, D. A.
Physics Education, v18 n6 p284-89 Nov 1983
Describes an interface designed to meet the requirements of an instrumentation teaching laboratory, particularly to develop computer-controlled digital circuitry while exploiting electrical drive properties of common transistor-transistor logic (TTL) devices, minimizing cost/number of components. Discusses decoding for Pet, switches, lights, and external input/output devices, including light-emitting diode (LED) displays. (JM)
