The Commodore PET (Personal Electronic Transactor) is a line of home/personal computers produced starting in 1977 by Commodore International.[2] A top-seller in the Canadian and United States educational markets, it was Commodore's first full-featured computer, and formed the basis for their entire 8-bit product line, including the Commodore 64. The first model, which was named the PET 2001, was presented to the public at the Winter Consumer Electronics Show in 1977.
