'Apple Computer A' prototype goes up for auction - and could sell for $500,000

'Apple Computer A', the prototype for the tech giant's first ever computer, is up for sale – and could sell for more than half a million dollars at auction. Considered'lost' until recently, the prototype was hand-soldered by Apple co-founder Steve Wozniak in 1976, the year the company was established. The'rare' and'historic' item is essentially a circuit board covered in chips and wires, embossed with the words'Apple Computer A 76'. It was a prototype for the Apple-1, the firm's first ever product, which was sold as an assembled circuit board and lacked basic features such as a keyboard or monitor. The prototype is now being sold off by RR Auction, an auction house based in Boston.
