RADIO SHACK

This brand started to make calculators in the 70’s by simply rebranding other company’s calculators. The

“game” here is to find which other brand has been sold under the Radio-Shack name.

A few examples:

CASIO CQ1 RADIO SHACK CHRONOMATH

CORVUS 400 RADIO SHACK EC-230 V.I.P. PROGRAMS – DATACAL II

KOSMOS ASTRO KOSMOS 2 RADIO SHACK EC-312 RADIO SHACK EC-314

:

I know of 138 different models of radio shack calculators, and I have 62 of this brand. I am sure I don’t

know all the models but as time goes by, I will complete this listing.
