The ATOMIX simulator is an advanced virtual Cold War era electro-mechanical rotor machine, situated between the Enigma cipher machine and the Fialka M-125. With its eight irregular stepping rotors, moving in both directions, the ATOMIX has a far better cryptographic strength as the Enigma and a tremendous key space. Its flexible pin settings provide many more different rotor movements than the Fialka. This very realistic virtual ATOMIX enables you to encipher and decipher messages, and apply the key settings as you would with an actual machine. As usual, available as freeware download on my site.
