Even to this day, people are still talking about the CP/M vs. MS-DOS controversy. Did MS-DOS steal from CP/M? Why did they settle a lawsuit if they didn’t? The problem is, almost no one realizes what the actual argument is. People want to make the issue about Microsoft stealing code from CP/M and using it. I don’t deny that there is a rumor that Gary Kildall performed some secret keystroke combination that produced an Easter egg in CP/M that he duplicated in MS-DOS. But, the best I can tell, that is complete folklore that only added to the mystique and mystery. The real argument is more apparent.
