Charles Ingerham Peddle

electrical engineer best known as the main designer of the MOS Technology 6502 microprocessor, the KIM-1 single-board computer, and its successor, the Commodore PET personal computer, both based on the 6502.[1][4][5][6]

Biography

Peddle was born in

radio station while in high school.[4]

In 1955, Peddle joined the United States Marine Corps. He attended the University of Maine where he earned a Bachelor of Science (B.Sc.) degree in engineering physics. Afterward, he went to work for General Electric working with time-sharing systems.[4]

In 1973, Peddle worked at Motorola on developing the 6800 processor.[4]

Peddle recognized a market for a very low price microprocessor and began to champion such a design to complement the $300 Motorola 6800. His efforts were frustrated by Motorola management and he was told to drop the project. He then left for

Oric computers, and the BBC Micro from Acorn Computers.[4][7] The Atari 2600 uses the closely related 6507 CPU, the Commodore 64 uses the also closely related derivative 6510, and the Nintendo Entertainment System uses a custom ASIC
which includes an altered 6502 core (with the decimal mode deleted).

The 6502 microprocessor design was also developed into the 16-bit

65C02S
and 65C816S, and microcontrollers based on each, are in production and available for purchase as of May 2023, over 47 years after the initial 650x introduction.

In 1980, Peddle left MOS Technology, together with

Victor 9000 personal computer.[7]

Legacy

Peddle, along with the 6502's co-designer Bill Mensch, are regarded as personal computer pioneers, in that both the 6502 technology and business model were instrumental in helping launch the personal computer revolution. After Peddle's death, Mensch wrote in memoriam.[8][9][10]
