A fully working Apple-I motherboard a number handwritten by Steve Jobs, plus all accessories, is expected to get $375,000 at auction.
Previously sold at auction for $375,000 in 2018, it's a "Byte Shop"- style Apple-I, meaning this is how it would have been delivered to that store in 1976. It has a number handwritten by Jobs.
"That Jobs numbered these himself is a recent revelation in the Apple-1 world," says the auction entry at RR Auction. "This computer is listed as #78 in the Apple-1 Registry, and was originally sold by RR Auction in 2018."
"The most remarkable aspect of this Apple-1 computer is that it is documented to be fully operational," continues the listing. "[The] system was operated without fault for approximately eight hours in a comprehensive test."
RR Auction says that a video of the test is available on request, as is "a comprehensive, technical condition report" by restorer Corey Cohen.
This Apple-I is part of an online auction that will end on December 16, 2022. At time of writing, it has a top bid of $219,615.
The same RR Auction also features a NeXT Computer brochure, signed by Jobs. It's expected to fetch $10,000.
Apple-I auctions now occur regularly, even if some are disputed.
