Microsoft co-founder says Bill Gates conspired against him

Microsoft Corp co-founder Paul Allen has accused his former business partner Bill Gates of plotting to dilute Allen's stake in the world's largest software company before he left in 1983, and tried to buy his share of the company on the cheap.

The launch of the book, "Man of Ideas: Proceedings of the cofounder of Microsoft") is scheduled for April 17.
Allen, who now runs a Seattle-based investment firm and philanthropic foundation, makes the claim in a forthcoming book of memoirs, excerpts from which were published in Vanity Fair magazine on Wednesday.
