Virtual Lorenz

The Lorenz SZ cipher attachment

COMING TO THIS SITE VERY SOON (IN THE FIRST HALF OF 2017)

Virtual Lorenz will be an online Virtual simulation of the Lorenz SZ40, SZ42A and SZ42B - the range of teleprinter cipher attachment machine developed by C. Lorenz AG in Berlin during World War II.

The Lorenz was what Bletchley Park code named "Tunny" and it was to break this machine that Colossus was eventually built by Tommy Flowers.
