August 3, 1977: The Tandy TRS-80 personal computer makes its debut. The first affordable, mass-market computer gives the Apple 1 some serious competition.
Although the TRS-80 arrived the year after the Apple 1 and a few months after the Apple II, it proved to be the first “Apple killer” on the market, predating later rivals like the IBM Personal Computer as Apple’s first big tech industry opponent. And, for the longest time, Tandy’s computer seemed to be on course to win.
