When Radio Shack announced its TRS-80 Model 1 on Aug 3, 1977, designer Steve Leininger thought they could sell 50,000 units. Tandy executives didn’t believe him. But the response overwhelmed the company, and 250,000 people put their money where their mouth was, paying $100 to get on a waiting list to buy one.
At the time, the median price of a Radio Shack product was $30. A TRS-80 bundled with a CRT display and tape drive cost $599 and was the most expensive product they had ever sold.
