Rare Apple I Returns to Auction

The "Hatfield" Apple I computer, which previously sold for $671,400 in 2013, is scheduled for auction this fall. Auction house Bonhams anticipates a sale price ranging from $500,000 to $800,000 for the device. This particular unit is named after its original owner, Fred Hatfield, who purchased it during Apple's first year of operation.

Historical Significance and Scarcity

The Apple I, listed as No. 48 on the Apple I Registry, is one of fewer than 75 surviving units, with even fewer remaining operational. The computer's motherboard bears the signature of Apple co-founder Steve Wozniak, who designed the machine. Buyers of the original Apple I had to provide their own power supply, keyboard, and monitor, and the device featured 4KB of RAM. Approximately 200 Apple I computers were produced.

Accompanying Steve Jobs Letter

The auction lot also includes a letter signed by Steve Jobs from 1978. In the letter, Jobs offered Hatfield a trade-in for an Apple II 4K board in response to a complaint about the lack of software for the Apple I. Hatfield declined the offer and later sold the Apple I to a collector for $40,000.
