The CCS is a co-operative venture between the British Computer Society, the Science Museum of London, the Museum of Science and Industry in Manchester, the National Museum of Computing and the Bletchley Park Trust.
The CCS was constituted in September 1989 as a Specialist Group of the BCS. It is thus covered by the Royal Charter and the charitable status of the BCS.

The aims of the CCS

• To promote the conservation, restoration and reconstruction of historic computers and to identify existing computers which may need to be archived in the future.
• To develop awareness of the importance of historic computers.
• To develop expertise in the conservation, restoration and reconstruction of historic computers.
• To represent the interests of Computer Conservation Society members with other bodies.
• To promote the study of historic computers, their use and the history of the computer industry.
• To publish information of relevance to these objectives for the information of Computer Conservation Society members and the wider public.

The museum at IBM Hursley Park exists to help preserve IBM’s historical heritage. The museum contains artefacts from the Hursley Park location as well as hardware from the company’s beginnings through to many of the products developed at Hursley over the years. Staff on-site can visit the museum at any time. Customer groups are often shown around the Museum during visits to the Executive Briefing Centre but due to its location in the IBM development laboratory the Museum is not open to the general public. However visits by organised groups can be, and are, arranged. Recent visitors have included several branches of the University of the Third Age (U3A), Chichester College,OGLE, the Computer Conservation Society and the National Museum of Computing (Bletchley Park). Applications for such visits should be made to uklabscomms@uk.ibm.com.

The Mobile Phone Museum project was conceived by Ben Wood in 2004. In 2019 he joined forces with fellow mobile phone collector, Matt Chatterley and a year later they worked with a small team to create a not-for-profit entity which is now a registered charity. This is designed to safeguard this important collection of mobile technology heritage and help fund further growth.

Pioneers of Computing

The University’s History of Computing Collection contains equipment, software, archives, ephemera, oral histories, and videos. It was founded, in Autumn 2007, in order to study historically technological development and innovation and, especially, the relationship between computing technologies and people and society.

One important focus is the development of computing in Wales. They have found that by investigating the local history of computing they are better able to see and try to understand the complicated interplay of technical, social, economic and cultural “causes and effects”.

The Collection is also interested in certain specialist areas of computing. The choice of these subjects reflects the interests of members of Swansea University and friends of the Collection. For example, they have an archive of L J Comrie, FRS (1893-1950), a pioneer of numerical methods, which contains notes and his collection of mathematical tables; and they have archives charting the development of theoretical computer science and formal methods for software engineering.
