IBM's enormous relay-based calculator, the SSEC, was one of a very small number of such machines, usually designed to solve specific problems. The SSEC is shown here at IBM world headquarters, 590 Madison Avenue, New York City, New York. Such early, massive calculators stimulated the popular imagination about the possibility of building "giant brains" or machines that could think.
