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 SSEM volunteers website , and also the webpages about the project about Rebuilding the Baby

Bombe Rebuild Project The rebuilt machine is now operational and can be seen at Bletchley Park. Please see the BP web site for more details. For more information about the rebuild project, click here.   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
 
     
Elliott 401 The CCS is restoring an Elliott 401 computer. This machine is not available to be seen by the general public at the moment.   Blythe House Rod Brown
 
     

Elliott

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
 
     
DEC The DEC project team is currently restoring a desktop 'straight' PDP8, the PDP11 Blacknest system, and the last remaining PDP11 based air traffic control system from LATCC, West Drayton.
See The National Museum of Computing for more details

The Harwell 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.

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 is working towards restoring this machine to full working order. It is regularly demonstrated and, although only half the machine is present (the other half is on display in the London Science Museum), is still viable.

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

An award application form is available to download from that site.

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      
 
     
Pegasus

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. For the time being it will remain on view in the Museum.
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.
