PET



"The microcomputer that's top of its class."

Commodore's Personal Electronic Transactor, or PET, was one of the "1977 trinity" - the first commercially successful personal computers, along with the Apple II and the TRS-80. Its low cost made it successful at first; but Commodore had production issues and they remained back-ordered for months. It was also a very weak hardware, and the keyboard was utter garbage.

As the PET's sales declined, Commodore soon planned a successor, which turned out to be the terrible VIC-20. After that, they redeemed themselves with the massively successful Commodore 64.
