A working Apple I computer has sold for $374,500 at a Friday Sotheby's auction, the BBC reports. The figure is over twice Sotheby's high estimate, and is the largest ever for an Apple I. Sotheby's comments that two parties ended up battling for the item: one through the auctioneer, acting on behalf of the absent collector, while the victor was a telephone bidder. Neither party has been identified publicly.
