Thanks Jm. I did buy the magazine and hope that will eventually lead me to a copy of the software with the 32 TTS-1. It also gave me some leads for a used copy from Ebay or other places. I may call the experts at B&H Photo and they may know the best version of Sonar or Calkwalk that will give me a 32-bit TTS-1 and also be installable on Windows 10.
