Electronic Delay Storage Automatic Calculator (EDSAC) was an early British computer.
Inspired by John von Neumann‘s seminal First Draft of a Report on the EDVAC, the machine was constructed byMaurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England. EDSAC was the second electronic digital stored-program computer to go into regular service.
EDSAC 1 was finally shut down on 11 July 1958, having been superseded by EDSAC 2, which remained in use until 1965.
The work flow of writing an EDSAC computer programme, generating the programme paper tape, and the execution of the program are presented with narration. If ever there was a compelling case for the creation of assemblers, compilers, and automated batch processing systems, this video is it.
