Recently-surfaced documents have led CNET to detail how Apple was able to transform its early products from hobbyist devices into bonafide computers. With the launch of the original Apple I, Steve Jobs and Steve Wozniak struck a chord with the hobbyist computer scene: it was a functional computer at a low price. The Apple I was sold without a case, power supply, or keyboard, and was never intended to take the world by storm. With the Apple II, though, Jobs had dreams of mass-market success. One thing standing in his way was the lack of a disk operating system (DOS), and although Wozniak believed he could write one himself, Jobs discovered Shepardson Microsystems, and negotiated a deal that saw the company code Apple's first DOS for $13,000 with no additional royalties. Six million Apple II sales later, the contract seems like one of the best deals Jobs ever made.
