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.

Emulation
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... )
