Steve Jobs’s original “Apple Computer A” prototype, hand-soldered by Steve Wozniak in 1976 and used to secure Apple’s first big order, is being auctioned at the moment.

Historic early prototype example of the computer that started it all—Steve Jobs’s own Apple-1 Computer prototype, hand-soldered by Steve Wozniak on a unique “Apple Computer A” printed circuit board. In 1976, Jobs used this prototype to demonstrate the Apple-1 to Paul Terrell, owner of The Byte Shop in Mountain View, California, one of the first personal computer stores in the world. The demo resulted in Apple Computer’s first big order and changed the course of the company—what Jobs and Woz had conceived as part of a $40 do-it-yourself kit for hobbyists became, at Terrell’s request, a fully assembled personal computer to be sold at $666.66.

It is being sold by RR Auction through August 18th online via this page.
