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.
Tandy TRS-80 launch brings first ‘Apple killer’ to market
The success of Tandy’s TRS-80 built on the promise of earlier personal computers, but benefitted from three main things: great distribution courtesy of the thousands of Tandy-owned Radio Shack stores around the United States; a relatively low price point of $599 (compared to $1,298 for an Apple II); and the fact that it was actually a pretty darn neat product.
Rather than simply eyeing the hobbyist market, Tandy targeted the TRS-80 at small businesses, the education market and regular consumers. Within days of its August 3 announcement at a press conference in New York City, the TRS-80 was already being hailed by the Associated Press as a home computer able to do “a payroll for up to 15 people in a small business, teach children mathematics, store your favorite recipes or keep track of an investment portfolio. It can also play cards.”
When it arrived for sale later in 1977, Tandy’s computer outsold the Apple II by a significant margin. It also beat Tandy’s own forecasts of 3,000 sales per year by selling more than 10,000 units in its first six weeks on sale. During the TRS-80’s lifetime, Tandy sold more than 200,000 of the machines.

Tandy TRS-80 finds immediate success
By 1981, when it was clear that personal computers were taking over, Time magazine described Apple as one of the new tech giants helping drive a $1 billion industry. But the first place on Time‘s list of tech giants went to Tandy:
“The Fort Worth-based Tandy Corp. has the broadest reach of any computer manufacturer through its 8,012 Radio Shack stores. The firm introduced its first small computer, the TRS–80, in 1977. A newer version of the TRS–80 (popular models now cost $999) has become the largest-selling computer of all time, and Tandy now commands 40% of the small-computer market. Tandy recently introduced the first pocket computer, which shows only one line of information and sells for $249.”
Licensing Mac OS to Tandy?
Interestingly, in a May 1982 private memo to Apple co-founder Steve Jobs, Apple marketing manager Mike Murray made what was probably the first proposal in Apple’s history to license the Mac’s operating system to Tandy for the TRS-80. (Bear in mind that the original Mac did not launch until two years later.)
“We would like the Macintosh user environment to become an industry standard,” Murray wrote. “The hitch, of course, is that now one must buy Mac hardware in order to get this user environment. Rarely (if ever) has one company been able to create and maintain an industry-wide standard that cannot be shared with other manufacturers.”
The argument was that Tandy drew a different type of customer than Apple did, and would therefore not cannibalize sales. Jobs declined the suggestion.
Although it’s often forgotten about today (Radio Shack filed for bankruptcy in 2015), the Tandy TRS-80 was an incredibly significant machine for its day. In 1977, it represented close to 70% of the total PC market, which is a stat that even the ubiquitous IBM PC couldn’t match until 1988. It remained the bestselling computer line until 1982.
