World War II Codebreaking Machine Restored

This news item lets the little Dieselpunk in me jump with joy:
The National Museum of Computing has finished restoring a Tunny machine, an allied cypher breaker of World War II.

The really infuriating thing about the matter:
They basically had to rebuild the whole apparatus from scratch. Most machines had been recycled and/or canibalized after the War… Even worse: Most of the schematics have also been lost, because the paper has been recycled (some as toilet paper) or simply thrown away… It’s a bit like NASA, they have deleted most of the original tapes of the Moon landings…

Anyway, the National Museum of Computing now has a working model as an exhibit and I think this an epic win for Dieselpunks and the place should be considered a Dieselpunk Shrine.

After all, these things are about as Dieselpunk as it gets, being highly advanced for their time and right inside the Dieselpunk time frame.

This is what the Tunny machine looks like:

and this is the German Lorenz Cypher (Lorenz-Schlüsselmaschine), whose code the Tunny was built to crack:

Quite an interesting piece of techology, too, the Lorenz Cypher. It is quite telling how much encryption you can acompolish without any digital equipment at all. And now think about modern encryption options ad modern code-breakers… Yes, another cycle that never ends…

Anyway: The BBC has several articles and videos regarding the restored Tunny, see it here (unfortunately, I cannot embed it).
