The Origins of Our Digital Age (22 November 2016)

Seven decades of computing progress have brought us from room-sized computers to wearable computing. At The National Museum of Computing on Bletchley Park this transformation can be seen in operational computers from each decade and proves a highly educational and entertaining resource.

Dr Andrew Herbert will focus on one particular computer: the 1949 EDSAC and show how one of key artefacts of the museum has come into being; over the past five years the project has researched and undertaken construction of a working reconstruction of EDSAC, the world’s first practical electronic digital computer.

The original, which no longer exists, was built at Cambridge University by a team led by M.V. Wilkes. Using circuits and technologies taken from Wilkes’ wartime experience with radar, EDSAC represents a transition from analogue to digital design.

Andrew will talk about how his team reconstructed the circuits from surviving documents and photographs, the challenges in recreating 70-year old technology, the benefits of doing so with modern electronics, and the impact the reconstruction has on visitors and the Museum’s educational programme.
