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 at document_exchange.htm.

Exciting news from Bletchley Park!

Agreement has been reached to transfer the Turing-Welchman Bombe Rebuild from the premises of the Bletchley Park Trust to those of the National Museum of Computing, still within the Bletchley Park estate.

John Harper, leader of the Bombe Rebuild team said “After careful consideration of the options, The Bombe Trustees approached TMNoC, which agreed to host the Bombe exhibit. We are delighted with this solution and welcome the opportunity to remain part of the overall visitor attraction at Bletchley Park. Our team of volunteers is looking forward to continuing to demonstrate how the Bombes made their vital contribution to Bletchley Park’s wartime role in the new venue. We thank the Bletchley Park Trust for their co-operation over the years and are pleased that the story of the Bombe will remain very much part of the story that it tells.”

Andrew Herbert, TNMoC chair responded “To house the reconstructed Bombe close to the Colossus Rebuild makes a lot of sense from many perspectives. As a pre-computing electro-mechanical device, the Bombe will help our visitors better understand the beginnings of computing and the general thought processes that led to the development of Colossus and subsequent computers. The story of the design of the Bombe by Alan Turing, the father of computer science, leads very appropriately into the eight decades of computing that we curate. Even the manufacture of the Bombes leads directly to British computing history – the originals were built by the British Tabulating Machine company (BTM) in Letchworth, which later became part of ICT, then ICL and now Fujitsu”

The Bombe will be housed near Colossus in a new gallery. A crowdfunding campaign to raise £50,000 has been sucessful and has exceeded its target. Many thanks to everybody who contributed.


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.
