CCS Projects

All of the practical work organised by the society is through project groups. Below is a list of the current projects, and a short summary of the sort of work they are undertaking.

Currently Active Projects

Group Name Summary   Based at Chair
Manchester Baby The project to build, demonstrate and maintain a replica of the Small-Scale Experimental Machine (SSEM)- the world's first computer.
For more see the the SSEM volunteers’ website. You may also find some webpages about the project at Rebuilding the Baby  
  Science & Industry Museum Chris Burton
Bombe Rebuild Project The rebuilt machine is operational and can currently be seen at the National Museum of Computing at Bletchley Park. The Bombe’s website is at   Bletchley Park John Harper
ICT 1301 An original 1961 machine is being brought back to life - see the ICT 1301 Resurrection web site for more details.   Currently in store awaiting a new home at TNMoC Rod Brown


This project team is responsible for a collection of Elliott 803, 903 and 905 computers. The TNMOC 803 and 903 machines can be seen working most weekends.   TNMoC Terry Froggatt
The Harwell Dekatron Computer
aka The WITCH Computer

This CCS project has restored the original Harwell computer (now the oldest working computer in the world) to working order, and maintains it on display to the public at the National Museum of Computing.

  TNMoC Delwyn Holroyd
ICL 2966

This project team is restoring an ICL 2966 mainframe at the National Museum of Computing.

  TNMoC Delwyn Holroyd
ICT/ICL 1900

An investigation into the remaining extant ICL 1900 Series machines with a view to cataloguing them and ascertaining whether restoration might be possible.

EDSAC Replica

This is a CCS project team set up to build a replica of the original Cambridge University EDSAC computer

Software Conservation The mission is the preservation of historic software in machine readable form, ideally along with execution capability. The focus is on long-term preservation rather than special effects on a PC.      David Holdsworth
The Tony Sale Award

An bi-annual award to recognise engineering achievement in the area of computer conservation - see the Sale Award website.

    Peta Walmisley
Bloodhound Missile/Ferranti Argus The centrepiece of this project is a Ferranti Argus computer installed as part of a missile control installation. Happily, there is no actual missile!

    Peter Harry
IBM Hursley Museum A large collection of IBM artifacts, many of them under restoration at IBM's Hursley House location and manned by volunteers. More details on the  UK Computer Museums webpage

Previous restoration and preservation projects
Mil-DAP Distributed Array (Parallel) Processor      

The Pegasus computer at the Science Museum was, for many years, the oldest extant working electronic computer in the world and was maintained and regularly demonstrated by a team of CCS members.. Since sustaining an electrical fault in 2009, Pegasus has not been demonstrated. The Science Museum authorities have now decided to retire it permanently and it has now been put into off-site storage.
Thanks are due to members of the CCS Project Team who have toiled valliantly to bring this venerable machine back to life and keep it that way for so long.

Elliott 401 The CCS was restoring an Elliott 401 computer. This machine is now on view (albeit not working) at the Science Museum in London.
The project has been abandoned for the time being.

The Hartree Differential Analyser

The Hartee Differential Analyser is a mechancal analogue calculator, built in the 1930s to solve partial differential equations. A small project team was working towards restoring this machine to full working order. It was regularly demonstrated and, although only half the machine is present (the other half is on display in the London Science Museum), is still viable.
Sadly the project was terminated by the machine’s owners the Museum of Science and Industry in Manchester as it no longer accords with their development plans and they can no longer afford the curatorial time to deal with the project. An associated project to re-activate the peripherals of a second Pegasus in the Museum and connect them to an emulator for the purposes of demonstration was terminated at the same time.

DEC The DEC project team has restored a desktop 'straight' PDP8, the PDP11 Blacknest system, and the last remaining PDP11 based air traffic control system from LATCC, West Drayton.
