In 1954, engineers at Philco Corporation invented the surface barrier transistor, the first transistor suitable for use in high-speed computers. Philco set up a computer activity—eventually a computer division—and in 1957 introduced the Philco Transac S-2000, the first large-scale, transistorized scientific computer system offered as a product by a computer manufacturer. In the spring of 1958, I was hired by Philco to organize a programming systems department to provide software support for the new computer system. This article presents part of the history of the Philco computer effort from one participant's point of view. Despite a number of successful installations, the Philco computer division lacked adequate resources to remain competitive in an area dominated by IBM, and Philco withdrew from the general-purpose computer field in 1965.
