John Sculley's salary won't cut into that net income any more, as he was officially replaced as chairman of the board last week by A.C. (Mike) Markkula, Apple co-founder and chairman of the board from 1977 through 1981. I won't dwell on whether or not Sculley left voluntarily, although he wasted little time in finding a new position as head of a company called Spectrum Information Technologies. No clue what they do.
