Radio Shack

Radio Shack (a Tandy corporation company) is a large US based store chain selling electronic products and parts. Similar to the other catalog distributors they sold and still sell calculators produced by other companies.Some of the early calculators sold by Radio Shack were produced by Texas Instruments. Nevertheless you'll find in the Datamath Calculator Museum some interesting products without any relationship to Texas Instruments. But they are from some evidence in the history of electronic calculators.
