Quoting from the Wired article: "A new book tackles modern computers in a uniquely hands-on way -- by getting the reader to build a replica of one of the most famous personal computers of all: the Apple I." "Apple I Replica Creation: Back to the Garage by Tom Owad explores the architecture of modern digital computers through the process of building an Apple I replica for about $100." Wired News, http://wired.com/news/mac/0,2125,66742,00.html?tw=wn_tophead_3 "The book focuses on the basic knowledge of digital electronics required to understand how the computer does its most basic work. Many diagrams and photographs illustrate specific tasks or functions. But the book is not simply a cookbook directing readers to "insert tab A into slot B." It attempts to teach the fundamentals of digital computer design along the way. The "Digital Logic" chapter, for example, which can be downloaded as a sample chapter (.pdf), shows how to build "and," "or" and "not" gates from resistors, diodes and LEDs. Owad said building microcomputers is within many readers' grasp, if they have the appropriate guide. "Apple I Replica Creation attempts to be that guide," Owad said.
