The Tunny decryption machine – on display at The Museum of National Computing at Bletchley Park, Buckinghamshire in the UK – was a feat of engineering both during World War II when it was created, and over the past five years when it was rebuilt by retired BT engineers."
The most difficult thing in the world is to know how to do a thing and to
