I remember that. I had hoped that CP/M would have become the premiere O/S. One of my military supervisors even had a personal computer that could boot both CP/M and MS-DOS. She preferred CP/M.
IBM wanted to license CP/M from Gary Kildall as the OS for their new IBM PC. Gary blew off the IBM meeting because he wanted to fly his private plane that day (weather was great). So IBM instead approached Bill Gates and the rest is history.
