Description

SWAC: Standards Western Automatic Computer. SWAC block diagram. "The plan was to build a computer with the minimum of circuit development. Thus, the circuits in the arithmetic unit were derived from Whirlwind circuits, and the development of the memory circuits depended heavily on the published work of F. C. Williams of Manchester University." Harry D. Huskey, "The National Bureau of Standards Western Automatic Computer, (SWAC)," Annals of the History of Computing, 1980.
