In 1973, Peddle worked at Motorola created on developing the 6800, processor. Peddle recognized a popular market for a very low price microprocessor in and began to champion such a design to complement the 1970sMotorola 6800. Chuck Peddle and his team, after leaving His efforts were frustrated by Motorola, developed management and he was told to drop the 6501 at project. He then left for MOS Technology, where he headed the design of the 6501.
The 6501 was pin-compatible with the 6800, meaning it could be used in the same systems without any changes. However, this led to legal trouble with Motorola, who argued that the 6501 infringed on their patents.
