I have a software package for running my N-Scale Layout, it was Purchased around 1995. According to the U.S Patent information, a Patent on or after 1995 expires in 20 years, before that it was 17 years,in a nut shell on these dates. If this is so, I would like to find someone who would like to help reverse engineer this. I like this system and still have all the parts and software needed and been using it all this time. Enough boards for a layout using 32 blocks and 32 turnouts/signals. It would take someone who has the ability to reverse engineer the software code on the system and come up with a way of making it work in today's technology (DCC). I have done many searches to make sure that this is not available and cannot find one spec of information. Attached is a picture of the layout and a little of the system This is a Loop-2-Loop design with 4 trains running on it at the same time (Bi-directional), also has a Point-2-Point trolley line with three trolley running at the same time. All power is DC only. The person who designed this was supposed to come out with a DCC upgrade but that did not happen. I am willing to answer all questions truthfully.
