A Magnetic-core Gate and its Application in a Stepping Register

Abstract

A magnetic-core gate to replace diodes is a necessity if an all-core computer is to be made feasible. A device is described composed of two magnetic cores and a resistance which will operate as a gate between the cores of a stepping register, replacing the diodes conventionally used. The theory of operation is presented, indicating an upper limit to the operating frequency of about 50 kc at present. A possible method of increasing the operating frequency is discussed.
