Tandy Corporation Radio Shack TRS-80
Tandy Corporation (Radio Shack) introduced the TRS-80, retroactively known as the Model I as the company expanded the line with more powerful models. The Model I combined motherboard and keyboard into one unit with a separate black-and-white monitor and power supply. Tandy's 3000+ Radio Shack storefronts ensured the computer would have widespread distribution and support (repair, upgrade, training services) that neither Apple nor Commodore could touch.
