An Apple-I computer, the first product made by the computing giant, has sold at auction for $375,000.
The machine was designed by Steve Wozniak, known as Woz, the co-founder of Apple.
His business partner, Steve Jobs, convinced him to package and sell the machine - it went on sale in 1976 for $666.66, according to a BBC report Wednesday.
It is one of only a handful of fully-functioning models known to be in existence today.
"The Apple-I was ghastly underpowered compared to the Apple-II," said Mr Wozniak in an email to the BBC on Tuesday.
"But this Apple-I computer showed the world the formula for an affordable USEFUL computer."
The auction took place in Boston, Massachusetts, on Tuesday. The buyer was an "anonymous businessman" who placed his bid online.
It is estimated that Mr Wozniak and Mr Jobs sold around 200 Apple-I computers in just under a year, thanks to a deal with a local computing store in Palo Alto, California.
According to an online registry - not affiliated with Apple - there are just 79 of the computers still around.
