Enigma-Cracking Bombe Recreated
toxcspdrmn writes "Volunteers at Bletchley Park have recreated a working replica of the electromechanical bombe used to crack the Germans' Enigma encryption. The bombe was designed by Polish cryptologists and refined by Alan Turing and colleagues at Bletchley Park. The replica joins a recreated electronic Colossus — generally considered the first electronic computer. Impressive work when you consider that Winston Churchill ordered the originals to be completely destroyed at the end of WWII."
It's truly a testiment to the brilliance of these people, that they were able to do so much with so little in the way of computing power. It's a shame that Alan Turing met such an unfortunate fate, with all he did for modern computing.

The actual approach to technology of the MOD is this:
Ignore British invention for 20 years or so
Buy it when it is produced in the US
Claim that British technology is inadequate and we must always follow the Americans.
And if you think I'm bitter about the Cocks encryption method (RSA), or the entire postwar history of British technology - yes, I am.

Yes Colossus is a digital computer. It was partially re-programmable. I think you were thinking of the bomba which is simply an Electro-Mechanical device.
Colossus was used to break the Lorenz SZ 40/42 cipher used for communicating between high level members of Hitler's regime. The Lorenz teleprinter had 12 rotors as opposed to the 4 wheels on the Enigma. The bomba was uses to break the 4 wheel Enigma.
Because the Colossus machine was highly classified for many years Tommy Flowers and his team were deprived of the recognition they deserve.
