CP/M-86 / MSDOS / DRDOS / GEM / Windows

I found the most interesting article on a web site about Gary Kildall, and that CP/M could have possibly been our main stream OS.. How could so many great ideas get lost in the big shuffle..? I know everyone has been talking about GUI's, and according to this article Digital Research did alot of work in this area. Also Digital Research back in 1989 released a very good DOS called DRDOS, I used this for awhile back in 1990 and was very impressed with its features, then MS came out with a clone of it called MSDOS ver 6.0.. I still own several original copies of DRDOS in unopened packages.. Check out this article its very interesting: http://www.microtec.net/~dlessard/kildall.htm Brings me to a question does anyone have a copy of the original DOS Version 1.0 ? I would love to load this on one of my old XT's .. Phil...
