This is the old software for the now defunct Cedar CD duplicators. To the best of my knowledge, it is now "public domain", as Rimage, which took over support for the Cedar line of CD duplicators disavowed any knowledge of it when I asked them about it. It will definately work with the DTP 1000, and should work with the DTP 800 and 4000, as they all use the same robotics and controllers. I do not believe it will work with any other model. It only runs under Windows 95/98/ME and 2000. It will definately NOT work under XP.
