This boxy calculator does not look like a Texas Instruments product. To identify it you should compare it with the Montgomery Ward P800 and the later Radio Shack EC-200.
If you look deeper into the calculator you'll notice that the EC-100 is very similar to the TI-2500 Datamath. This Radio Shack EC-100 is once again a calculator using the famous Texas Instruments Klixon™ keyboard technology.
The EC-100 was soon replaced with the EC-200, nevertheless did we discover a variation of the EC-100 with a slightly different keyboard.
Datamath™ and Klixon™ are trademarks of Texas Instruments.
