About this collection

Dedicated on August 17, 1950 at the Institute for Numerical Analysis at UCLA, the Standards Western Automatic Computer (SWAC) was the companion computer to the SEAC (Standards Eastern Automatic Computer). It was to handle special problems of the aircraft industry on the west coast for the Navy Department, as well as engineering, physics, and mathematical calculations required by the National Bureau of Standards and by other Federal agencies in the area. The SWAC was quite different in logical design and construction, being a parallel machine in which all the digits of a number in memory are changed simultaneously, had electrostatic memory rather than mercury-delay-line memory, and also used a magnetic drum memory.
