This book is an exciting history of the personal computer revolution. Early personal computing, the "first" personal computer, invention of the micrprocessor at Intel and the first microcomputer are detailed. It also traces the evolution of the personal computer from the software hacker, to its use as a consumer appliance on the Internet. This is the only book that provides such comprehensive coverage. It not only describes the hardware and software, but also the companies and people who made it happen.

The mastermind behind Apple sheds his low profile and steps forward to tell his story for the first time. Before cell phones that fit in the palm of your hand and slim laptops that fit snugly into briefcases, computers were like strange, alien vending machines. They had cryptic switches, punch cards and pages of encoded output. But in 1975, a young engineering wizard named Steve Wozniak had an idea: What if you combined computer circuitry with a regular typewriter keyboard and a video screen? The result was the first true personal computer, the Apple I, a widely affordable machine that anyone could understand and figure out how to use. Wozniak's life-before and after Apple-is a "home-brew" mix of brilliant discovery and adventure, as an engineer, a concert promoter, a fifth-grade teacher, a philanthropist, and an irrepressible prankster. From the invention of the first personal computer to the rise of Apple as an industry giant, iWoz presents a no-holds-barred, rollicking, firsthand account of the humanist inventor who ignited the computer revolution.

The late Seventies to the early Nineties was a completely unique period in the history of computing. Long before Microsoft and Intel ruled the PC world, a disparate variety of home computers, from an unlikely array of suppliers, were engaging in a battle that would shape the industry for years to come.Products from established electronics giants clashed with machines which often appeared to have been (or actually were) assembled in a backyard shed by an eccentric inventor. University professors were competing head to head with students in their parents' garages.Compatibility? Forget it! Each of these computers was its own machine and had no intention of talking to anything else. The same could be said of their owners, in fact, who passionately defended their machines with a belief that verged on the religious.This book tells the story behind 40 classic home computers of an infamous decade, from the dreams and inspiration, through passionate inventors and corporate power struggles, to their final inevitable demise. It takes a detailed look at every important computer from the start of the home computer revolution with the MITS Altair, to the NeXT cube, pehaps the last serious challenger in the personal computer marketplace. In the thirteen years between the launch of those systems, there has never been a more frenetic period of technical advance, refinement, and marketing, and this book covers all the important steps made on both sides of the Atlantic. Whether it's the miniaturization of the Sinclair machines, the gaming prowess of the Amiga, or the fermenting war between Apple Computer, "Big Blue, " and "the cloners, " we've got it covered. Digital Retro is an essential read for anyone who owned a home computer in the Eighties.

This book will help you troubleshoot your laptop problem and take the most cost effective approach to repairing it, getting it repaired, or replacing it. But the troubleshooting process depends on your observations of the symptoms and your willingness to keep your mind open to solutions other than your first impression, or those suggested by friends who say they had "exactly the same problem." If the laptop is still usable but acts up, pay close attention to when and where it acts up, whether the problem always occurs after the laptop has been moved, or shut-down for the night, or running all day. Even the weather plays a part in troubleshooting some problems, so try to read through all of the general troubleshooting sections, just to get a feel for the things that go wrong with different components. If it doesn't make you into a laptop hypochondriac, it will make you a stronger diagnostician.You may notice we don't talk about the razzle-dazzle technology of computer components in this book. The reason is simple. You can't upgrade or repair your laptop by using the latest technology available, nor can you save money by repairing it with older technology rescued from a random laptop at the recycling center. You have to use the exact parts your laptop was engineered to work with. Hard drives and memory are the only replaceable parts that are often compatible between models of a similar vintage. For some readers, the lack of an illustrated discussion on how hard drives store data bits will take some fun out of the book, but that knowledge can't help you when it comes to troubleshooting. There are plenty of books with beautiful color illustrations that try to explain basic computer technology, but they do so at the expense of helping you solve real laptop problems.Two final notes about using this workbook. First, if your laptop is in warranty, it doesn't make any sense to take it apart in hopes of fixing something yourself. This book can still help you troubleshoot the problem to determine if it's a software setting or incorrect use, which may save you sending the laptop out for repair. Second, feel free to cut out the twelve flowcharts in the second half of the book and staple them together. This will save on page flipping as you read the expanded explanations of the decision symbols. It's a workbook, not English literature.The Laptop Repair Workbook includes twelve full page troubleshooting flowcharts for laptop hardware troubleshooting and explanatory text for every decision point. The book begins with an introduction to basic laptop terminology, troubleshooting procedures, and cost decisions. Supplementary illustrated tests and procedures are available on the publisher's website and an ebook version is also available direct from the publisher.

Technologies have a life cycle, says Donald Norman, and companies and their products must change as they pass from youth to maturity. Alas, the computer industry thinks it is still in its rebellious teenage years, exulting in technical complexity. Customers want change. They are ready for products that offer convenience, ease of use, and pleasure. The technology should be invisible, hidden from sight.In this book, Norman shows why the computer is so difficult to use and why this complexity is fundamental to its nature. The only answer, says Norman, is to start over again, to develop information appliances that fit people's needs and lives. To do this companies must change the way they develop products. They need to start with an understanding of people: user needs first, technology last--the opposite of how things are done now. Companies need a human-centered development process, even if it means reorganizing the entire company. This book shows how.
