A US recycling centre is looking for a woman who dropped off an old Apple computer that turned out to be worth 200,000 dollars (£130,000).
The computer was inside boxes of electronics that she had cleaned out from her garage after her husband died, said Victor Gichun, the vice president of Clean Bay Area, in California's Silicon Valley.
She did not want a tax receipt or leave her contact information, and it was not until a few weeks later that workers opened the boxes to discover a highly collectible Apple I computer inside.
The San Jose Mercury News reports it was one of only about 200 first-generation desktop computers assembled by Steve Jobs, Steve Wozniak and Ron Wayne in 1976.
"We really couldn't believe our eyes. We thought it was fake," Mr Gichun told KNTV-TV.
The Milpitas-based recycling firm sold the Apple I for 200,000 dollars to a private collection, and because the company gives 50% of items sold back to the original owner, Mr Gichun said he wants to split the proceeds with the mystery donor.
He said he remembers what she looks like and is asking her to come back to claim her 100,000 dollar (£65,000) cheque.
