What if you led a revolution and no one noticed? In 1975, the brilliant twenty-five-year-old engineer Mike Wise and a few hand-picked associates started Sphere Corporation in the sleepy suburb of Bountiful, Utah. Together, they designed and delivered a pioneering desktop personal computer, two years before Apple, Commodore, and Radio Shack popularized the idea. But after selling over a thousand systems, Sphere crumbled and fell through the cracks of history-until now. Based on extensive interviews and archival material, Go Computer Now! tells the lost story of Sphere: The rise and fall of a scrappy and ambitious company; its remarkable, flawed computers; and the influential community of customers who kept their cathode-ray screens glowing long after Sphere's own offices went dark. It is also the story of Mike Wise, an imperfect visionary who poured energy and rare inventiveness into a company that couldn't quite deliver then watched from afar as others found fame and fortune in the future of his imagining. Bill Gates remembered Sphere. So did Steve Wozniak. In this compelling book, Ben Zotto asks whether you should, too. An engaging read for both the computer-history aficionado and a general audience, Go Computer Now! is profusely illustrated in full-color with archival, newly commissioned, and never-before-seen photography.
