EDSAC (Electronic Delay Storage Automatic Calculator)

EDSAC (Electronic Delay Storage Automatic Calculator) was the world's first practical general purpose stored program electronic computer. It was designed in 1947 by a team lead by Maurice Wilkes. The original EDSAC computer operated for almost 10 years; its first successful program ran on 6th May 1949, at the Cambridge University Mathematical Laboratory. A working replica of EDSAC (pictured) can be found as an exhibit in The National Museum of Computing's unrivalled collection.
