One of the first Apple computers ever built, and forerunner of today's MacBooks, iPads and iPhones, goes up for auction at Christie's next week.
The Apple 1 from 1976 was designed by two college dropouts Steve Jobs and Steve Wozniak who went on to create one of the world'd biggest companies. The computer could fetch more than £300,000.
It's owned by a retired school psychologist in the United States who has kept it stashed away in a cardboard box at his home outside Sacramento, California.
- The green piece of plastic covered with a copper-coloured labyrinth of memory chips was one of the first 25 such computer elements, and sold for $666.66 (£430)
- About 200 were made but most have disappeared or been discarded
- Various estimates put the number known to still exist from about 30 to 50
- They came with eight kilobytes of memory - a million times less than the average computer today
Tery Perry got his Apple computer in either 1979 as a second-hand item he saw advertised. He paid nothing for it, it was just a swap with the owner.
At an earlier action in May, a working Apple 1 computer fetched £440,000 at auction.
