Apple 1 The Apple 1 was sold as an exposed motherboard

A rare functioning Apple 1 computer - the company's first product - has
been sold at an auction for $374,500 (�240,929).

....

A memo written by the firm's co-founder Steve Jobs when he worked at
Atari sold for $27,500 at the same New York event.

....

Only about 200 Apple 1s were ever created. The computers were hand-built
by Apple's co-founder Steve Wozniak and originally sold for $666.66
(�426) as a fully assembled circuit board.

He later said he picked a sum with a repeating number "because it was
just an easier way to type".

Only about 50 Apple 1s are still believed to be in existence. The
auctioned model is one of the very few that still works.
