The computer, rather a circuit board, was manufactured in 1976 and is offered complete with a MOS 6502 8-bit, 1 MHz CPU. Included are the cassette interface, which was a $75 option for the base board that sold for $666.66, the operation manual for the Apple 1, as well as a preliminary Apple BASIC user manual. Sotheby's estimates the value of the system at $120,000 to $180,000.
Only about 50 of the originally sold 200 systems are still believed to have survived until today. Italian collector Marco Boglione bought an Apple 1 in November 2010 at a Christie's auction. That lot also came with the original invoice as well as a personal letter from Apple co-founder Steve Jobs.
