Robert Bruce Thompson is a coauthor of Building the Perfect PC and PC Hardware in a Nutshell. Robert built his first computer in 1976 from discrete chips. It had 256 bytes of memory, used toggle switches and LEDs for I/O, ran at less than 1MHz, and had no operating system. Since then, he has bought, built, upgraded, and repaired hundreds of PCs for himself, employers, customers, friends, and clients. Robert reads mysteries and nonfiction for relaxation, but only on cloudy nights. He spends most clear, moonless nights outdoors with his 10-inch Dobsonian reflector telescope, hunting down faint fuzzies, and is currently designing a larger truss-tube Dobsonian (computerized, of course) that he plans to build. Barbara Fritchman Thompson is a coauthor of Building the Perfect PC and PC Hardware in a Nutshell. Barbara worked for 20 years as a librarian before starting her own home-based consulting practice, Research Solutions, and is also a researcher for the law firm Womble, Carlyle, Sandridge, & Rice, PLLC. During her leisure hours, Barbara reads, works out, plays golf, and, like Robert, is an avid amateur astronomer.
