Andy Rathbone started geeking around with computers in 1985 when he bought a 26-pound portable CP/M Kaypro 2X. Like other nerds of the day, he soon began plying with null-modem adapters, dialing computer bulletin boards, and working part-time at Radio Shack. He wrote articles for various techie publications before moving to computer books in 1992. He's written the Windows For Dummies series, Upgrading and Fixing PCs For Dummies, TiVo For Dummies, PCs: The Missing Manual, and many other computer books. Today, he has more than 15 million copies of his books in print, and they've been translated into more than 30 languages. You can reach Andy at his Web site, www.andyrathbone.com.
