SSEC Delivers Speed, Memory, and Programability
IBM's Selective Sequence Electronic Calculator, introduced in 1948, boasted processing speed, memory, computational capacity, and programmability. The Control Desk seen here was the tip of the iceberg. The rest of the machine surrounded the operator, lining all four walls of a large room. The SSEC is said to be the first computer that could modify a stored program. IBM invited university professors and scientific researchers to use the device at no charge at an IBM facility--a good-will gesture that generally stoked demand for computer purchases.
