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 1 MHz, 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 non-fiction 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.
