(CBS San Francisco) — A piece of computer history dating back four decades is about to hit the auction block and is expected to fetch a six-figure price.

Boston-based RR Auction is auctioning off an original Apple-1 computer, dating back to the late 1970s. The computer reportedly is a machine made by company co-founders Steve Jobs and Steve Wozniak for The Byte Shop in Mountain View, one of the first computer stores in the world.

Auction organizers expect the Apple-1 would fetch at least $300,000 when it goes up for bid in late September.

The company’s first device helped paved the way for what would become a Silicon Valley powerhouse. Recently, the Cupertino-based tech giant became the nation’s first publicly traded company worth $1 trillion.

Jobs and Wozniak produced about 200 Apple-1 computers, about 60 of which still exist today, according to CNET.
