The EDSAC Replica Project aims to reconstruct one of the most important early British digital computers.

Designed in 1947 by a team lead by Maurice Wilkes, the original EDSAC computer operated for almost 10 years, starting from its first successful program run on 6th May 1949, at the Cambridge University Mathematical Laboratory.

We are now initially targeting to have a working reconstruction of EDSAC as it was in 1951 (when it was in everyday service at the University of Cambridge Mathematical Laboratory) operational in summer 2018.

The story of the project is being told through a series of short videos.

The EDSAC Replica Project is a registered charity and is affiliated to the UK’s Computer Conservation Society.
