excellent reproduction of the WWII German code machine

Pros
it is utterly faithful to the mechanics and feel of the WWII Enigma Machine.
Cons
i can appreciate the attention to making this feel as realistic as the way that codes had to be entered/decoded back then, but how about adding some, and i stress this, OPTIONAL automation to the process?
Summary
Amazing simulator, faithful and realistic. Would like to see some of the other variations of the Enigma that came out during the end of the War. Some automation would be cool, too.
A realistic Enigma simulation

Summary
This review was originally posted on VersionTracker.com.<br />As a newbee on Mac OS X, I've been on the lookout for an Enigma Simulator ever since I purchased my MacBook Pro. Being interested in historical cipher machines, and the Enigma in particular, I like to study the mechanical and electrical properties of these devices. High quality - reliable - simulators have been around for some time both Windows and RISC OS, but unfortunately not for the Mac. Until now that is... I was pleasantly surprised when I learned about Terry Long's new Enigma Simulator for Mac OS X, so I downloaded it immediately. Being only 1MB, it's a fairly small application which installs in seconds. After that, the Enigma is just a click away. Once started it presents a large window, containing what looks and feels like a real Enigma machine. The cosmetics are very good and the program is very intuitive to use. It currently simulates only the Naval three-wheel Enigma (M3), which is 'compatible' with the standard German Army service machine, albeit with letters on the wheels rather than numbers. At present, the famous Stecker board hasn't been implemented, nor is the Ringstellung, but apart from that, it is absolutely wonderful. If you bare in mind that this is the first real application the author has ever written on a computer, it's a promise for the future. If you are interested in the history behind the Enigma machine, and want to explore it on your favourite OS, don't hesitate and download it immediately. And watch this space for future enhancements. Oh yes, and don't forget to motivate the author for adding additional features.

Developer’s Description

enigma cipher simulator with steckerbrett & file input/output

Enigma Simulator is a program that simulates the use of Enigma ciphering machines that were commonly used by Nazi Germany during World War II. It enciphers text exactly the same as would a real Enigma machine and includes Steckerbrett and the ability to import/export text to many formats. Now Enigma Simulator also includes AppleScript support and automatic updating.
