The Radio Shack EC-3001 printing calculator is a copy of the well-known Texas Instruments TI-5050M portable printing calculator. It has 5 AA NiCd rechargeable batteries inside and used an AC9171 AC adapter. It uses thermal paper for printing.

This calculator has been refurbished and its batteries have been replaced. The calculator works as can be seen in the images.

The calculator comes with its charger and soft carry case. A roll of paper is in the calculator already, regular modern thermal paper can be used also.
