Experience with the use of the British Standard Interface in computer peripherals and communication systems

Abstract

The new British Standard Specification(1) 4421 entitled “A Digital Input/Output Interface for Data Collection Systems” is gaining wide recognition in the United Kingdom and has been submitted to the International Standards Organisation for International appraisal. Although the B.S. Interface has been described elsewhere (5)(6)(7) a brief outline is given here to facilitate the subsequent discussion of its applications to computer peripherals, small computers, and the NPL data network.
