Return of Colossus to mark D-Day
Colossus Mk2, a wartime code-breaker hailed as one of the first electronic computers, has been rebuilt and reunited with Bletchley Park veterans.
Colossus was also ground-breaking because it was put into action two years ahead of its nearest US rival, the Eniac (Electronic Numerical Integrator and Computer).
Although, Mr Sale said, Eniac was thought to have been first because Colossus was kept a secret until the 1970s.
