Colossus was a famous and top secret code breaking computer from WW II.

The Colossus Rebuild Project was started by Team Leader Anthony E Sale Hon FBCS and has taken 10 years and has involved over 6,000 man-days of volunteer effort. At a conservative daily rate of £200 this gives a value of £1.2 Million for the Colossus Mk 2 Rebuild.

The Rebuild is now working and can demonstrate most of the code breaking work against the German Lorenz cipher in WW II.

The Rebuild stands in its historically correct place, the room in H Block, in Bletchley Park, UK where Colossus No. 9 stood in WW II.
