O’Reilly has announced the release of “Revolution in the Valley” by Macintosh co-creator Andy Hertzfeld. The US$24.95 hardcover book “traces the development of the Macintosh, from its inception as an underground skunkworks project in 1979 to its triumphant introduction in 1984 and beyond. The stories in the book come on good authority: Hertzfeld, a core member of the team that built the Macintosh system software and a key creator of is radical user interface, was one of the chosen few who worked on the project with Steve Jobs. You might call him the ultimate insider.”
