Apple's founding papers have been sold at auction for $1,594,500 (£1.03m). Sotheby's had estimated the three typed partnership agreements would sell for between $100,000 and$150,000. The documents were signed by the firm's three co-founders, Steve Jobs, Steve Wozniak and Ronald Wayne on 1 April 1976. The papers include an amendment added 11 days later when Mr Wayne quit. The buyer was Eduardo Cisneros, chief executive of Cisneros Corporation.
