The Radio Shack EC-3004 is identical with the Texas Instruments TI-5025

The backside of the EC-3004 looks very familiar to us. It makes use of the original TI-5025 mold and hides its true genes under a small label.

The EC-3001 and the EC-3004 were the last Texas Instruments printing desktop calculator sold under the Radio Shack brand, later models based on far-east OEM products.
