ElectroData Corporation

ElectroData originated as a part of Consolidated Electrodynamics Corporation (CEC), which manufactured scientific equipment.

Clifford Berry and Sibyl M. Rock developed an analog computer to process the output of CEC's mass spectrometer.

In 1951 CEC enlisted Harry Huskey, who managed the development of the SWAC computer on the project.

In 1954 the first model of the computer, now named the Datatron 203 shipped to the Jet Propulsion Laboratory in Pasadena.

By 1956 ElectroData was the third-largest computer manufacturer in the world, but was unable to generate enough revenue to meet the demands of growing the business.
