Working Apple-1 computer up for auction

An Apple-1 computer in working condition is up for auction at Bonhams.

The rare lot will headline a science and technology auction in New York on September 21, with a valuation of $300,000-500,000.

The Apple 1 computer is one of 66 surviving specimens

It's one of a handful of early models built by Steve Wozniak in his parents' garage in 1976. All buyers were offered a free upgrade to the Apple II soon after its release, meaning that original working specimens are rare.

Only 66 are known to have survived, of which 17 remain operational.

Bonhams explains the exceptional provenance of the lot: "The superlative rarity of an Apple-1 in this condition is corroborated by this machine's early history.

"The owner, Tom Romkey, owned the 'Personal Computer Store' in Florida, and was certified as an Apple level 1 technician in 1981.

"One day, a customer came into his shop and traded in his Apple-1 computer for a brand new NCR Personal Computer.

"The customer had only used the Apple-1 once or twice, and Mr. Romkey set it on a shelf, and did not touch it again."

The record for an Apple-1 stands at $905,000, paid by the Henry Ford Museum at Bonhams in 2014.
