In the year 1982 Texas Instruments had some difficulties to decide whether a calculator was a BASIC one or a SCIENTIFIC one. We know some pairs of similar calculators sold in both fields:
confusion could be noticed with the Integrated Circuits used in these early

Toshiba IC's you'll discover in the TI-1020 a Sharp LI3009 and in this TI-1744
the brain was developed by NEC (Japan).
