Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

I guess you could call it an "Enigma"

I guess you could call it an "Enigma"

#1 Post by Rapidrob » Mon Sep 30, 2019 3:54 pm

I just came back from a 'Nam reunion in Washington D.C. On the way back to my old stomping grounds we stopped by Ft. Meade and the NSA Museum.
Inside is all sorts or really neat Crypto gear and some very interesting stories.
Around one corner was a WWII German Enigma en/de-coding machine that is fully functional! your allowed to play with it and code/de-code messages which I did.
Very easy to use by changing the "Code Wheels" which the Germans would change out each day.
After you place the code wheels to today's numerical setting you punch in the code and your message is encoded. A lamp is light for each letter letting you know what letter is now a code letter. Reversing the action brakes the code allowing you to read the message.
The mathematical combinations that can be reached for coding letters is greater than all the sand grains on the worlds beaches.
The machine that broke the code is also on hand to be seen.
A fun free museum that is worth the stop. You also get a ton of free really nice pamphlets to read about NSA's greatest achievements.

The "G" is light and you'd write that down for the Radioman to send out.

Here is my message encoded for "NM MILSURPS"

I just got back from the Heritage Air & Armor facility in Everett, WA. They had one. Very cool stuff. PAX

No idea on that.
That have several machines you could play with. None of course of my time as they are still classified.
