Enigma Machine
The Enigma Machine

Although it is hoped that one day we can open a real museum here at the institute, for the moment that is not possible. In the mean time, we will try to photograph the equipment that we have and document it as best as we can so that you can enjoy the museum from your home or office, wheresoever you may be. At the moment we have an Enigma Machine on loan, which we have fully documented. The texts will follow, but the pictures are already available.
