World’s first calculator using Film Carrier System and yellow LCD. In the same year Sharp introduced the EL-8026, the first calculator powered by solar cells.

A similar calculator to the EL-8020 was introduced one year later with the TI-1750 manufactured by Texas Instruments. Don't miss the EL-8024 featuring a yellow LCD and an external AC adapter.

The Sharp EL-8020 uses a small Film Carrier System for the calculator chip to achieve a slim design. EL-8020_LCD.jpg (79557 Byte)
