Hi Bob I see you are in Perth, just wondering if you can help me? I am in Armadale. A while back I can into possession of a Domiteux 300 engraver, with the cipher system. The machine is all there, including the the cipher key. This machine dates back into the 1990`s. I myself know nothing about mechanical engravers, I got it for my daughter to learn how to engrave etc. It did come with what I think was the software on a CD. Sadly this was corrupt as we could not open it... tried it on numerous computers going back to windows 98. Would you know where I might be able to locate this software.. In the cipher manual it is called 1x bundled cipher software.The manual itself was printed after 1993. thanking you regards Don McDouall doolyoz@gmail.com
