Paul Allen says book not revenge against Gates

(AP) -- Microsoft co-founder Paul Allen defends his new book in an upcoming episode of "60 Minutes." He says it was meant as an important slice of technology history and not as revenge against Bill Gates.

Allen, who left Microsoft in 1983, tells Lesley Stahl of "60 Minutes" that he wanted to tell that history the way it happened. In video excerpt CBS posted on its website, Allen says he hopes people understand this.

But for all the harsh pictures he paints of Gates, Allen reveals another side, too. Gates, who now focuses on philanthropy, comforted Allen when he got cancer a second time in 2009. Says Allen: "there's a bond there that can't be denied."

Allen's book, "Idea Man," hits shelves Tuesday. The "60 Minutes" episode airs Sunday.
