The Commodore PET (Personal Electronic Transactor) is a line of home/personal computers produced starting in 1977 by Commodore International. 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 the first personal computer ever made available to retail consumers.

“Commodore were a company previously known for their calculators, and had acquired chip company, MOS in 1976 to ensure they had a steady supply of integrated circuits for them. MOS’s Chuck Peddle became Commodore’s chief engineer and persuaded Commodore head, Jack Tramiel to enter into the microcomputer market, and the PET was born.

The Commodore PET was part of what BYTE Magazine dubbed the “1977 Trinity”, alongside the Apple II and Tandy’s TRS-80.
## Emul
Emulating the PET can be done using the VICE emulator, which is available on many platforms and as well as the PET, will also emulate all of Commodore’s 8-bit machines. One thing to be aware of when emulating the PET is that all the numbers were in the numeric keypad (there wasn’t a separate row on the top of the main keyboard), so if you find that numbers aren’t working, try the numeric keypad. (If you have one… )
