First Apple home computer to be sold at auction

An Apple I computer, created by Steve Jobs and Steve Wozniak in 1976, is estimated to fetch between $120,000 and $180,000 when it goes up for auction at Sotheby's later this month.

The computer is a rare working example of the first Apple computer with the original cassette interface, operating manuals and rare BASIC Users' Manual.

The Apple 1 heralded the start of the personal computing revolution by allowing users to type letters on a keyboard rather than through a panel of lights and switches.

The item was sold for $666.66 but did not include the monitor, keyboard, power supply or case that makes up the modern computer.

There are thought to be fewer than 50 of these computers in existence, and only six are known to be in working condition.
