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:
Same
confusion could be noticed with the Integrated Cicuits used in these early
calculators manufactured in Taiwan. Instead the usual
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).
