Computer history - 1948
Major computer events in 1948
The world's first stored-program computer, the SSEM (Small Scale Experimental Machine), nicknamed the "Manchester Baby," was built by Tom Kilburn at the University of Manchester, England. Kilburn's first stored program, which calculated the largest factor of an integer by repeated subtraction, was successfully executed by the SSEM on June 21, 1948.
Other computer events in 1948
IBM's first large-scale digital calculating machine, the SSEC (Selective Sequence Electronic Calculator), was announced. The SSEC was the first computer to modify a stored program featuring 12,000 vacuum tubes and 21,000 electromechanical relays.
IBM introduced the IBM 604 Electronic Calculating Punch. The mass-produced 604 features the industry's first assemblage of digital electronics replaceable as a unit. Service engineers can pull out a defective unit of the 604 and plug in a replacement, reducing downtime.
