Abstract

Digital calculator interface circuit is designed for the control of an action exterior to the calculator. The interface has metallised connexion holes and members for connexions with other interface circuits or circuit components. The interface has integrated circuits, hybrid components etc. and the interface typically controls a relay or a lamp.
