The Commodore PET, first announced in January 1977, is recognized as the world’s first personal computer, preceding the Apple II and TRS-80. It featured a fully integrated design with a keyboard, monochrome monitor, MOS 6502 processor, built-in BASIC operating system from Microsoft, cassette tape storage, and expansion ports, all housed in a durable metal or plastic chassis. Developed under Chuck Peddle’s leadership and launched by Commodore after acquiring MOS Technologies, the PET was revolutionary for providing a complete, ready-to-use personal computing system that spurred early home and educational computer adoption before eventually evolving into various improved models and becoming a foundation for Commodore’s later successes.
