MOS Technology, Inc., also known as CSG (Commodore Semiconductor Group), was a semiconductor design and fabrication company based in Norristown, Pennsylvania, in the United States. It is most famous for its 6502 microprocessor, and various designs for Commodore International's range of home computers.
MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor) was originally started up to provide a second source for Texas Instruments designed electronic calculators and the chips inside them. They also produced Atari's custom Pong chip for a short time. As the calculator market grew MOS eventually became largely beholden to Commodore Business Machines, who bought practically all of their supply for their line of calculators.
Things changed dramatically in 1975. Several of the designers of the Motorola 6800 left the company shortly after its release, apparently in disgust. At the time there was no such thing as a "design-only" firm (known as a fabless semiconductor company...
