Wiki Photo: The Hand built Apple-1
The Apple-1 computer was hand build in Steve Wozniak's parents garage. Steve Job's came up with the idea of selling it. The Apple-1 was first demonstrated in April 1976 at the HomeBrew Computer Club in Palo Alto.
Originally, the Apple 1 sold for $500 when it was sold to a reseller 1976. It was made out of wood and was billed as the first "personal computer." The retailer marked up the Apple-1 by 33% giving it a price of $666.66.
An Apple I reportedly sold for $50,000 USD at auction in 1999, with another apparently selling in 2009 for $17,500.
Fast forward to November 2010. This same Apple I (with serial number 82) sold for $178,000 ($213,600 including the 'buyer's premium') at Christie's auction house in London , making it by far the highest price paid for this model to date, at £133,250 ($210,000).
The high value of this particular example is likely due to the rare documents and packaging offered in the sale rather than the computer itself; namely (and amongst others) the original packaging (with the return label showing Steve Jobs' parents address, the original Apple Computer Inc 'headquarters' being their garage), a personally typed and signed letter from Jobs (answering technical questions about the computer) and the original invoice showing 'Steven' as the salesman.
