With the goal of establishing applicability of microprocessors in fields which have traditionally relied upon electromagnetic relays for logic functions, one of the commercially available microprocessor assemblies was interfaced with a specially designed display panel to illustrate the concept of a microprocessor controlled railway signaling interlock. The MPU was programmed to scan the status of the simulated block occupancy switches and display appropriate speed signals.
