The IBM Card-Programmed Electronic Calculator was announced in May 1949 as a versatile general purpose computer designed to perform any predetermined sequence of arithmetical operations coded on standard 80-column punched cards. It was also capable of selecting and following one of several sequences of instructions as a result of operations already performed, and it could store instructions for self-programmed operation. It could add figures at the rate of 2,174 a minute.
