Computer history is one of my favorite topics, so I've read a lot over the years. Here's my list:

>> Classic computer history:

- "Hackers: Heroes of the Computer Revolution", Steven Levy

- "The Innovators", Walter Isaacson

- "Valley of Genius: The Uncensored History of Silicon Valley", Adam Fisher [innovative format, tons of interesting tidbits after you get used to the style. Read only after the other two above]

- "The New New Thing: A Silicon Valley Story", Michael Lewis

- "The Second Coming of Steve Jobs", Alan Deutschman

- "Revolution in The Valley: The Insanely Great Story of How the Mac Was Made", Andy Hertzfeld

- "Masters of Doom", David Kushner

- "Idea Man", Paul Allen

- "Where Wizards Stay Up Late", Katie Hafner

>> Entertaining stories, but less historical value:

- "Ghost in the Wires", Kevin Mitnick

- "Chaos Monkeys: Obscene Fortune and Random Failure in Silicon Valley", Antonio Garcia Martinez

- "Hatching Twitter: A True Story of Money, Power, Friendship, and Betrayal", Nick Bilton

>> On my to-read queue:

- "How the Internet Happened", Brian McCullough [just started; very promising]

- "Troublemakers: Silicon Valley's Coming of Age", Leslie Berlin

- "Code Girls: The Untold Story of the American Women Code Breakers of WWII", Liza Mundy

- "Fire in the Valley: The Making of The Personal Computer", Paul Freiberger / Michael Swaine

>> Others worth mentioning (but just read a few chapters):

- "The Supermen: The Story of Seymour Cray", Charles Murray [about Cray Computers]

- "Racing the Beam" [about Atari]

- "Commodore: A Company on the Edge" [about Commodore]

>> Bonus:

- "Art of Atari", Tim Lapetino [great as a coffee table book, particularly if you grew up in the 80's :) ]
