Application of Relay Logic Techniques to Simplify Systems Simulation

An application is given of mechanical and electrical simplified relay logic techniques for simulating a solid state computer. The basic requirements of any simulation system are simplicity, reliability, maintainability, flexibility, and realism which can be readily satisfied, in most cases, by the use of relay logic techniques. Modular construction of twelve relays prewired to a connector facilitate changing a programmed sequence at the training instructor's discretion. The relay logic is the nucleus of this type of simulation system.
