Abstract :
There is a large field of application of digital-computing techniques where reliability and simplicity are far more important than speed. A basic circuit is described which uses one transistor, one capacitor and three resistors, from which a complete digital-computing system may be constructed economically. A system using this circuit is extremely simple to design, construct and maintain, and should prove very reliable, although it cannot achieve the speed of operation of systems using more complex circuits. The way in which well-known computer circuits are constructed from this basic circuit is described, and an account is given of a complete logical system, employing 184 such circuits, which was constructed to demonstrate their application.
