ENIAC Computer Retired
After eleven years of calculating and processing programs, the ENIAC was retired. Designers John Mauchly and J. Presper Eckert had unveiled the machine in February 1946, showing off its 1,000-time improvement in speed over its contemporaries. The ENIAC ran at 5,000 operations a second with a system of plug boards, switches, and punch cards. It occupied 1,000 square feet of floor space.
