Thanks to all, This project is, indeed, for my own educational purposes. I have always been "all idea, no action" type of person. It's time for me to act on my ideas. I have started by comparing the differences between Unix V7, 32V, Coherent, and NetBSD code base. I wish to preserve as much of Unix V7 as possible. Unix V7 was not without code contributed by others, namely Universities around the world. I don't know the legal logistics, but I don't see any reason to change the name from Unix V7 to anything else. As I begin to make run time progress on this project, I will keep everybody notified. I will also be posting questions as they arise. Thank you, James Falknor (I know I'm not alone with a World of Programmers on this mailing list)
