An Apple-1 computer dating to 1976 is up for auction in California, and the auctioneers said they expect it to fetch up to $600,000.
John Moran Auctioneers said the Apple-1, which was designed by Steve Wozniak and assembled and tested by Steve Jobs, had two previous owners before going on the auction block.
The lot comes with a Datanetics Keyboard Rev D, a 1986 Panasonic video monitor, some relevant cords, an Apple-1 Basic Manual, the Apple-1 Operations Guide, an MOS 6502 programming manual and two Apple-1 software cassette tapes.
Only 200 Apple-1 computers were ever made by Jobs and Wozniak. A working Apple-1 sold for $671,000 when it was auctioned in Germany in 2013.
The auction house said bidding opened Tuesday morning.
