The hunt is on for a woman who dumped an old Apple computer valued at $A261,470 ($US200,000).
A recycling centre in the Silicon Valley says the woman who dropped off the computer obviously had no idea it was a rare collectible.
Victor Gichun of Clean Bay Area says the woman left boxes of electronics that she had cleaned out from her garage after her husband died.
It wasn’t until a few weeks later that workers at the recycling centre opened the boxes to discover an Apple I computer inside.
The San Jose Mercury News reports it was one of only about 200 first-generation Apple computers made in 1976.
Gichun sold the computer to a private collection, and he wants to split the proceeds with the mystery donor.
