The Ferranti Pegasus computer at the London Science Museum, operated and maintained by members of the CCS, is the oldest working extant electronic computer in the world.

Founded in 1989, the Computer Conservation Society is a joint venture between the British Computer Society, the Science Museum and the Museum of Science and Industry in Manchester.

Our primary mission is to preserve historic computers, develop awareness of the history of computing, and encourage research.

We run many specialised working groups, organise a public lecture series, and publish a regular bulletin.
