This week in 1982, Compaq announced the first true IBM PC clone — it was portable, too, as long as you were comfortable lugging 28 pounds

In 1982, Compaq introduced the first true IBM PC clone, the Compaq Portable, which was also portable but weighed 28 pounds. It featured a reverse-engineered IBM BIOS for near 100% compatibility with IBM PC applications. The Compaq Portable's success kick-started the PC clone industry and inspired a new era of PC enthusiasts. Despite IBM's later entry into the portable PC market, Compaq's innovative product paved the way for the industry's growth.
