IBM Ad for SAGE, A Massive Cold War Air Defense System (1960)


This 1960 IBM ad touts the capabilities of SAGE, a massive Cold War-era automated system for tracking and destroying incoming enemy bombers. The heart of the system was the IBM AN/FSQ-7 computer, which at 275 tons is still the world’s largest computer. Each computer had 55,000 vacuum tubes, required a half acre of floor space, and operated on punch cards. There were 52 AN/FSQ-7 computers around the country. SAGE was retired in the early 1980s.
