With out an reasonably priced CPU, Steve Wozniak would possibly by no means have invented the Apple computer systems that launched a technological revolution. Woz’s machine and plenty of of its friends have been powered by the work of Chuck Peddle.

Peddle, {an electrical} engineer and former Marine, joined Motorola in 1973. There, he helped develop the 6800, a robust however costly microprocessor. When he noticed potential prospects balk at its $175 price ticket (greater than $1,000 in 2020 {dollars}), he got down to develop a low-cost various.

After his pitch was rejected by Motorola, Peddle recruited a half-dozen of his colleagues — nearly half of the 6800 workforce — to hitch him at MOS Expertise, the place Peddle led the efforts to develop a brand new chip.

In 1975, MOS launched the 6502, an 8-bit microprocessor that offered for simply $25, a seventh of the 6800’s price. Its affordability and flexibility led to it powering dozens of early house electronics, amongst them the Apple II, the Commodore 64, the Atari 2600, and the Nintendo Leisure System. An enhanced model of the chip, the 65C02, continues to be accessible from Western Design Middle.

When Commodore bought MOS in 1976, Peddle was put accountable for growing a private pc constructed across the 6502. The outcome was 1977’s Commodore PET. In 1980, Peddle left MOS to co-found Sirius Methods Expertise, the place he invented the Victor 9000 pc.

Peddle died at 82.

Editor’s observe: Peddle died in December 2019, too late to be included in final 12 months’s “Tech luminaries we misplaced” slideshow.
