Silicon Wafer with 6502 Microprocessor Chips - 4 inch, Rockwell, MOS

About this Artwork: This silicon wafer was fabricated by Rockwell International in the mid-1980s. This wafer contains the Rockwell version of the MOS 6502 microprocessor. The wafer has about 410 microprocessors on it. Adjusted for inflation, the price per chip would be about $80, giving the wafer a value of about $32,800. After Motorola introduced the 6800, some of Motorola’s designers left to start MOS Technologies. Introduced in 1975, the 6502 processor was MOS’s first successful product. Although influenced by the design philosophy of the 6800, the 6502 is clearly a different and more advanced chip design. More important to its success though, the 6502 was designed as part of a whole family of 6500 series processors. The 6502 was the heart of several early microcomputers and game systems. Commodore, Apple, and Atari were among the 6502 designs. Apple designer, Steve Wozniak, described it as the first chip you could get for less than a hundred dollars (a quarter of the 6800 price). I
