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.

April 2016

Saturday 24th September 2016 – Guided Visit to the Ferranti Argus 700 Restoration Project - RAF Cosford (between Shrewsbury and Wolverhampton)

Meeting point at 11:30 am. The tour is estimated to last for about two hours.

The Argus 700 is a computer that gained a reputation from industrial control and a variety of simulators, both civilian and military. Following a four-year restoration project, a Cold War simulator, with its Argus 700, has been fully restored. The restored simulator at RAF Cosford was used in the Bloodhound missile system to train controllers in the defence of the United Kingdom during the Cold War.

The visit will include an overview of the Argus 700 and the challenges faced in restoring it to full working order, why it was used in the Bloodhound system, and how the Argus architecture meets the requirements of control systems. The simulator will be operating, lifting the lid on one aspect of the Cold War of which the general public knew very little.

Please note that it is located in a hangar on the airfield, where it can be cold and damp, and where toilet facilities are limited (Reception is a better bet!).

RAF Cosford is a secure area (and a completely separate site to the RAF Museum, about 10 minutes’ drive away, where there is a café for before or after the visit). Specific instructions for checking in will be issued nearer the time. As this an MOD site, visitors must be registered in advance, and security passes must be issued on arrival. RAF Cosford will need to know full names of attendees, and car details if you are coming by car (there is a car parking charge). Any queries, please contact Peter Harry, Bloodhound Missile Preservation Group . The website

If you would like to attend, please email Rachel Burnett by 31st August, as numbers are restricted.

Pegasus at the V&A

The Computer Conservation Society has, until recently been working with the London Science Museum and the Museum of Science and Industry in Manchester on the Pegasus computers which each of these institutions own. Sadly these projects have had to be halted for want of museum resources. You might wonder what has happened to these two historic machines.

The Science Museum Pegasus has gone into store and there are at present, no plans to exhibit it again.

The Manchester machine has been lent to the Victoria & Albert Museum (just accross the road from the Science Museum — the irony is not lost on us) to be a part of Engineering the World: Ove Arup and the Philosophy of Total Design a new exhibition which runs until the 6th of November.

It is understood that Ove Arup used a Pegasus (not the same one) to help design the Sydney Opera House.


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.
