On the 80th anniversary If you are interested in learning about Colossus and how it was used to decode Lorenz SZ40 encrypted traffic during WWII.

Some elements of the design are fascinating and predate much later design of computers for speed and ingenuity.

The following is a talk by Chris Shore at the Centre for Computing History which gives the story and operation of Colossus in some detail 😀
