Guided Tour of The National Museum of Computing, Bletchley Park

The Group had a most interesting 2 hour tour of The National Museum of Computing, Bletchley Park, led by Mr Robert Dowell. This covered the evolution of computing and software technology from the Colossus of WWII decrypting German Enigma and Lorentz codes, through all the decades since, culminating in devices such as the present-day IBM PC, the Apple Mac, iPad, smartphones, etc.

A number of the intervening devices were shown in operation, particularly the Harwell Dekatron (WITCH). The phenomenal advances in processor power, computer memory and hardware architecture were fully illustrated. In conclusion, a  fascinating demonstration of a simulated air traffic control centre was shown.
