BBC News: Code-cracking Tunny machine returned to life

Excerpt:

Quote:

The National Museum of Computing has finished restoring a Tunny machine - a key part of Allied code-cracking during World War II.

Tunny machines helped to unscramble Allied interceptions of the encrypted orders Hitler sent to his generals.

The rebuild was completed even though almost no circuit diagrams or parts of the original machines survived.

Intelligence gathered via code-cracking at Bletchley underpinned the success of Allied operations to end WWII.
