Electronics engineer
Chuck Peddle is mostly known as the main designer of the
MOS Technology 6502 microprocessor; the
KIM-1 SBC; and its successor the
Commodore PET school/business/home computer, both based on the 6502.
Peddle had worked at
Motorola from 1973 on the development of the
6800 processor but then left for
MOS Technology, where he headed the design of the
650x family of processors; these were made as an answer to the
Motorola 6800. The most famous member of the 650x series was the 6502, which was subsequently used in very many microcomputer devices (four well-known examples from the consumer market being the
Apple II, the
Commodore VIC-20, the
Nintendo Entertainment System aka NES and the ATARI 8-bit computers).
The 6502 has also been "tweaked" to support other computers while maintaining
backwards compatibility. Such examples are the 6510 used in the
Commodore 64.
Peddle left the company in 1980 together with CBM financer Chris Fish to found
Sirius Systems Technology. There, Peddle designed the
Victor 9000 personal computer/workstation.
