The gavel is coming down on Apple this summer - on the auction block.
Only half of the original 200 are still in working condition.
The circuit board is expected to fetch $180,000 at auction.
Also on the auction block is a memo written by Steve Jobs during his days at Atari.
The memo includes changes the Apple co-founder thought could be made to Atari's World Cup soccer arcade game.
The memo was written two years before Jobs founded Apple.
It is expected to go for at least $10,000 at auction.
