EDSAC was an early British computer developed by Professor Sir Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England and completed in 1949.

This is one of a set of photographs showing computers, computer components, computer structure diagrams and computer programmimg instructions, probably used as aids in teaching computing subjects. The diagrams and instructions relate to several pioneer models and systems of stored program computers dating back as far as the 1950s and including CSIRAC (originally known as CSIR Mark 1), Cirrus, Atlas, IBM System/360 , CDC 6600 System, and Illiac IV.
