One of the first batch of Apple personal computers has sold at auction in London for 133,250. The Apple I came with its original packaging and a signed sales letter from Apple co-founder and current chief executive Steve Jobs. The computer, one of only 200 of the model ever made, originally sold for $666.66 when it was introduced in 1976. It was bought over the phone at Christies by Italian businessman and private collector Marco Boglione. Francesco Boglione, who was at the auction house on Tuesday, said his brother had bid for the piece of technology history because he loves computers. BBC Another of Apples co-founders, Steve Wozniak, who was also present and agreed to add an autographed letter to the lot, said: Im very delighted for the gentleman who purchased it. Francesco Boglione said it was likely that the Apple I - also known as the Apple 1 - would be returned to working order before joining a collection of Apple computers. Christies said the Apple I had been the only personal computer to come with a fully assembled motherboard when it was introduced, making it ready to use straight from the box. However, the user needed to provide a keyboard, power supply and display. Despite its high auction value, the Apple Is processor works 1,000 times slower than todays Apple iPad. Also up for auction at Christies were papers published by World War II codebreaker Alan Turing, but they failed to sell, raising hopes they could be kept in the UK. The Manchester University scientist created a machine at Bletchley Park to crack messages in the German Enigma code. The failure to reach a reserve price means a campaign to raise funds to buy the papers for the Bletchley Park Trust for public display in the UK will continue. BBC
