Hi all, I've not been around for quite a while but just got back to playing SHIII last night. This may have been mentioned before and if it has them accept my apologies but in case it hasn't. I found this link to a piece of software that creates a codebook for various versions of Enigma simulators found at the same site as this link. The codebooks can be made for one day, a month or a year. As an added immersion feature I thought some of you guys might be interested.

I haven't yet tried the codebook software myself but I have used the Enigma simulator and it is very good
