If Ron Wayne, now 76, weren't one of the most luckless men in the history of Silicon Valley, it wouldn't have turned out like this.He was present at the birth of cool on April Fool's Day, 1976: Co-founder — along with Steve Jobs and Steve Wozniak — of the Apple Computer Inc., Wayne designed the company's original logo, wrote the manual for the Apple I computer, and drafted the fledgling company's partnership agreement.That agreement gave him a 10 percent ownership stake in Apple, a position that would be worth about $22 billion today if Wayne had held onto it.
