  ABSTRACT: For years, rumors have circulated that the code for the original DOS operating system created by Microsoft for the IBM personal computer is actually copied from the CP/M operating system developed by Digital Research Incorporated. In this paper, scientifically tested and accepted forensic analysis mathematical techniques, step-by-step processes, and advanced software code comparison tools are used to compare early versions of the two code bases. The conclusion is reached that no copying of code takes place1.
