Apple II Handbook Signed by Steve Jobs Sold For $787,484

If you thought Apple laptops were expensive, wait until you see the price of their manuals. On Thursday, an Apple II manual signed by late co-founder Steve Jobs sold for $787,484 at RR Auction in Boston.

Mike Markkula, Apple’s second CEO and an early investor, has also signed it. While Jobs and Markkula were in the UK promoting Apple, Julian Brewer, the son of an entrepreneur who worked with Apple to sell their products, received the autographed manual.

The Apple II, debuted in 1977, was the company’s first successful product and is primarily regarded as one of the first mass-market computers. In addition, the first computer spreadsheet, VisiCalc, was created for the Apple II in 1979, extending the computer’s popularity to the corporate world.
