Unlike later personal computers, including the 1977 Apple II, the Apple-1 was sold as a fully-assembled circuit board, but minus a case, power supply, keyboard or monitor. Buyers had to provide those components, resulting in some interesting customizations. Christie's Apple-1 is mounted on a wooden board, as are a modern keyboard and the power supply.
All Apple-1s were hand-built by Apple co-founder Steve Wozniak in 1976. They sold then for $666.66, equivalent to $2,724 in today's dollars, or more than a top-of-the-line 15-in. MacBook Pro with a Retina-quality display goes for now.
The one to be sold by Christie's is hand-signed by Wozniak, as are the included manual and board schematics.
Christie's Apple-1 will be exhibited at the Computer History Museum in Mountain View, Calif., June 24-27. The online auction runs from June 24 to July 9.
Christie's will put this Apple-1 on the block in an online auction that begins June 24, and has pegged the likely sales price between $300,000 and $500,000.
