Tandy Corporation’s Radio Shack division was responsible for the development of the TRS-80 (Tandy Radio Shack- 80) home computer. The TRS-80 is remembered fondly as an underpowered but affordable home computer. Whilst Tandy’s computer may not have been as sophisticated as its competitors, such as the Apple, the TRS-80 had advantages beyond its low cost. Tandy’s Radio Shack stores offered a readymade distribution network for software. Its popularity with home coders meant that there was plenty of software available for the TRS-80.
Tandy liked to ensure that Radio Shack was dominated by Tandy products to ensure profitability and published a suite of software for the TRS-80.
