Notes: Tony Sale on WW2 codebreaking and Colossus rebuild

Earlier this evening I went to a great lecture by Tony Sale, on “Code Breaking in World War 2″.

He discussed Enigma, and how it was broken, then the Lorenz cipher/machine, and how that was broken, and then the Colossus, leading to the Colossus rebuild project. He should know about this stuff: he started the project.

I took some notes if anyone is interested [PDF, 76Kb] (naturally, these are rough notes, may contain errors, are my own, etc.). You might also want to check out which includes a virtual Colossus.
