This is why I'm still skeptical about the claims that it's "impossible" for there to be a CP/M easter egg in CP/M, as Kildall claimed there was (although I think the likelihood of the same egg in MS-DOS is zero).

Then again, all we have is one person claiming that they witnessed it, and since Gary Kildall himself dropped the case against Microsoft and never bothered to push it, we probably will never know for certain.
