From its inception in 1957, Digital Equipment Corporation (DEC), headquartered in Maynard, Massachusetts, carved itself a role in American business unlike any other company. Launched by Massachusetts Institute of Technology engineer Ken Olsen with a $70,000 investment from the country's first venture capital firm, DEC rapidly became a pioneer in computer technology. In its heyday, DEC had a valuation of more than $12 billion and employed approximately one hundred twenty thousand people worldwide, making it second only to IBM. Its people and technology contributed to making computers increasingly affordable, which led directly to the advent of the personal computer, the first computer games, and computer networks. DEC was also a leader in the Internet revolution, claiming the dubious distinction of launching the first spam mailing and registering one of the first commercial domain names. Through photographs of people, events, and machines, Digital Equipment Corporation tells the story of the unassuming computer revolutionaries who reshaped the technological world. It is written for anyone who is interested in how the present era of computing ubiquity has evolved since the 1940s, when IBM chairman Thomas Watson predicted that the whole world might need no more than five computers.

For some time there has been a need for a semiconductor device book that carries diode and transistor theory beyond an introductory level and yet has space to touch on a wider range of semiconductor device principles and applica tions. Such topics are covered in specialized monographs numbering many hun dreds, but the voluminous nature of this literature limits access for students. This book is the outcome of attempts to develop a broad course on devices and integrated electronics for university students at about senior-year level. The edu cational prerequisites are an introductory course in semiconductor junction and transistor concepts, and a course on analog and digital circuits that has intro duced the concepts of rectification, amplification, oscillators, modulation and logic and SWitching circuits. The book should also be of value to professional engineers and physicists because of both, the information included and the de tailed guide to the literature given by the references. The aim has been to bring some measure of order into the subject area examined and to provide a basic structure from which teachers may develop themes that are of most interest to students and themselves. Semiconductor devices and integrated circuits are reviewed and fundamental factors that control power levels, frequency, speed, size and cost are discussed. The text also briefly mentions how devices are used and presents circuits and comments on representative applications. Thus, the book seeks a balance be tween the extremes of device physics and circuit design.
