The first Apple computer — together with a letter signed by Apple Inc. CEO Steve Jobs to the original owner — will be sold at a London auction this month.
Described by Christie's as a "historic relic," the Apple-1 was introduced in 1976 and sold without a casing, power supply, keyboard or monitor.
But it was the first personal computer with a fully assembled motherboard, at a time when personal computers were sold as self-assembly kits.
The first Apple-1 computers were priced at $666.66 and were dispatched from Jobs' parents' house.
The auction house said Friday the item is rare because all the components are still in their original box and came with a letter signed by Jobs.
It will be sold on Nov. 23 and is expected to fetch up to 150,000 pounds ($242,400.)
