Main logic asembly board of Commodore PET 2001, 1979.

Exhibited at the Consumer Electronics Show in the United States in January 1977, the Commodore PET (Personal Electronic Transactor) was one of the first consumer-level microcomputers to be launched. Together with the Apple II and the Radio Shack TS 80, the PET revolutionised home computing. It was a popular machine and three models were made with increasing memory capacity: the PET 2001-8N (with 8 KB RAM), the PET 2001-16N (with 16 KB RAM ) and the PET 2001-32N (with 32KB RAM). The SuperPET, which followed in 1981, was the first computer to have coprocesors. Manufactured by Commodore Busines Machines, United States.
