September 13, 1983: Osborne Computer Corporation, one of Apple’s early rivals, declares bankruptcy.

Many consider the company’s Osborne 1 the world’s first truly portable, full-featured computer. It packed everything users needed to set up shop at home or on the road. Alas, it didn’t last!

March 3, 1975: The Homebrew Computer Club, a hobbyist group that helps spark the personal computing revolution, holds it first meeting in Menlo Park, California.

It becomes a welcome forum for computer geeks at a time when few others cared. And regular attendee Steve Wozniak and his friend Steve Jobs will eventually show off the first Apple-1 unit at the club.

February 7, 1981: Apple co-founder Steve Wozniak is involved in a serious plane crash, resulting in his first lengthy leave of absence from the company.

At the time, Wozniak is flying a turbocharged, single-engine, six-seat Beechcraft Bonanza A36TC. In the plane with Woz is his fiancé, Candi Clark, her brother and her brother’s girlfriend. Fortunately, nobody dies in the crash, although Woz suffers minor head injuries.

August 25, 2016: An ultra-rare Apple-1 computer raises $815,000 in a charity auction, one of the highest prices ever paid for one of the machines. Bidding actually reaches $1.2 million in the auction’s final minutes. However, that bid gets pulled seconds before a winner is announced.

The reason for the super-high price? This “Celebration” Apple-1 boasts a feature that did not appear on any production models of the computer.
