Commodore PET – The Worlds First Personal Computer

The Commodore PET, first announced in January 1977 at the Consumer Electronics Show, was the world's first personal computer, predating the Apple II and Radio Shack TRS-80. Designed by visionary engineer Chuck Peddle, the PET came fully equipped with an integrated monitor, keyboard with numeric pad, 1 MHz processor, 4K of memory, cassette drive, and expansion ports—all housed in a steel chassis. The prototype was hastily assembled in the week before the show, with Peddle working 20-hour days to complete it just hours before the exhibition opened.
