John Roach, a marketing visionary who helped make the home computer ubiquitous in the late 1970s by introducing the fully assembled Tandy TRS-80 for $599.95 or less through RadioShack chain stores, passed away on Sunday in Fort Worth. He was 83.
He was instrumental in prodding Tandy to venture into the computer market. At the time, most small computers were sold as kits to be assembled by hobbyists, but Mr. Roach believed that consumers would welcome a model that they just needed to plug in.
His team presented the original TRS-80 prototype — cobbled together from a black-and-white RCA monitor, a keyboard and a videocassette recorder — to Tandy’s chief executive, Charles Tandy, and to Lewis Kornfeld, the president of RadioShack, in January 1977.
At just under $600 (about $2,700 in today’s dollars), the computer was relatively cheap (it was $399 if connected to a separately owned viewing screen). It was available in all 8,000 of the company’s stores.
