NYADS was largely responsible for one of the foundational projects of the computer era: the development of the SAGE, the Semi-Automatic Ground Environment air defense system. SAGE was devised to collect and coordinate all available information on the local air situation and dissemination of battle instructions to defending forces at electronic speeds. Aside from the strategic importance, SAGE set the foundation for mass data-processing systems and foreshadowed many computer developments of the 1960s. The heart of the system, the IBM built AN/FSQ-7, was the first computer to have an internal memory composed of magnetic cores. SAGE also
