Historic Document Rescue

From time to time the Society is approached by people who have come into the possession of documents relevant to historic computers and who feel that they should “go to a good home”.

Unfortunately the Computer Conservation Society is no longer in a position to collect such material, though we can often suggest a suitable home for it. If you have a need to dispose of historic material we suggest that you should first read our guide Archives and your Personal Papers.

In particular, we should stress that a list of the document titles is essential before any progress can be made.


Document Exchange within the CCS

Because CCS members use widely differing IT systems, difficulties sometimes arise when documents are sent between members. In an attempt to minimise such problems a page of guidance notes can be found document_exchange.htm.

LEO Exhibition in Cambridge

To mark the 70th anniversary of the start of the LEO Computers project, The Centre for Computing History in Cambridge is holding an exhibition starting 11th November 2017 to explore how developing the LEO Computers allowed Lyons to take the lead in applying computers to the world of business.

The first LEO was heavily based on the Cambridge EDSAC and, in fact, the forward-thinking Lyons part-funded EDSAC’s development so that they could produce a version themselves for commercial purposes. Lyons handed over the funds to Maurice Wilkes on 11th November 1947 and this exhibition opens on the 70th anniversary of that event.

Members of the LEO Society will be at the museum for the weekend of 11/12th November to talk to visitors about what is was really like working with the LEO computers and there’ll be some rare LEO hardware and documentation on display. The exhibition will bring together the objects CCH holds along with some items on loan from the LEO Society and Corby Heritage Centre to tell the story of this extraordinary company and the computerised business world they helped create.

Admission to the exhibition is free as part of the standard museum entry charges so you can see the whole museum when you visit.

Making IT Work Conference Proceedings

The edited proceeding of last May’s Making IT Work conference are now available at MIW 2017.pdf.


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 projects, organise public lecture series, and publish a regular bulletin.

Membership of the society is open to all.
