Not only will Sotheby’s be selling the Steve Jobs memo to Atari, but they will also be auctioning off a working Apple-1 computer. There are only 50 left in existence, of which 6 are currently working. The Apple-1 was originally sold as a logic board for $666. It is being projected that the Apple-1 will be auctioned off somewhere between $120,000 and $180,000 next month. [Source: TUAW]
