It's unlikely to reach the lofty heights of the Qianlong Chinese porcelain vase that was sold for £43m at auction recently, but an original Apple I should still fetch a pretty penny when it goes under the hammer later this month.

The hobbyist machine, that first went on sale in July 1976 for $666.66, is expected to reach between £100 to £200k.

It is one of only 30-50 left in the world, out of an original stock of 200 that were hand-built by Apple co-founder Steve Wozniak.

The machine was designed for early computer enthusiasts and was first demoed at the Homebrew Computer Club in Palo Alto, California.

The Apple I comprised of a fully assembled circuit board with around 60 chips on board. Users had to add a case, a power supply and switch, an ASCII keyboard, and a video display to make a operational machine.

The auction lot contains the computer in its original shipping box with a return address marked as Steve Jobs' parents' house. It also includes a signed letter from Jobs, the operation manual and the cassette interface.

The auction takes place at Christie's on 23 November. Pocket-lint would like to start the bidding at £10.50.
