A working Apple 1, the first range of computers sold by the US powerhouse, has realised a world record $374,500 at a Sotheby's auction in New York.
Of the 200 produced in 1976 and the 50 believed to be in existence, just six are thought to still be operational.
The computer beat its high estimate of $180,000 by 108% at the June 15 sale, and surpassed the previous record of $213,000 by 75.8%, set in 2010.
The value rise is even more impressive when one considers that the version that sold in 2010 was accompanied by a receipt signed by the company's founder, Steve Jobs.
The sale is a firm indication that the passion for collectors of technology from Apple's early days is at an all-time high, with last year's passing of Steve Jobs no doubt bringing an influx of nostalgic buyers into the market.
"When Steve Wozniak and Steve Jobs presented the Apple 1 Computer to the Homebrew Computer Club in 1976, it was dismissed by everyone but Paul Terrell, the owner of a chain of stores called Byte Shop," said Sotheby's of the computer.
"Terrell ordered 50 computers for $500 apiece."
The Sotheby's auction also featured a 1974 memo from Jobs detailing ways to improve the Atari World Cup Soccer arcade game.
The four page report and accompanying note to the games manufacturer sold for $27,500, well up on its $15,000 high estimate.
In December the Jobs-signed 1976 contract which established the first Apple partnership made $1.6m, also at Sotheby's New York.
