6 pp., including covers; illustrated; 4to. Minimal soiling along egdes; faint musty smell. [c. 1957.] A vintage marketing brochure for a milestone in computer science. Though undated, content suggests that this is one of the earlier brochures, refering to the transac S-2000 as "an entirely new concept in electronic digital computers." "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."
