Remarkable how early TI's LCD model was.

TI may have had some help from Toshiba with their early basic and scientific LCD calculators.

"Concerning LCD-calculators Texas Instruments was far behind Japanese companies. Sharp Corporation started sales already in the year 1973 with the EL-805 sporting a silver-colored COS-LCD display. If you restrict the comparison on the first calculator using the yellow-screen FEM-type display you find the Casio's Pocket LC introduced in the year 1975, the Sharp EL-8020, Toshiba's LC-810 and finally the Canon LC-1."
