We wrote the year 1982 when Texas Instruments discovered the lower labour costs of Taiwan, R.O.C. compared to US or Europe. Up to 1982 most calculators of Texas Instruments were produced either in US or Italy and some early LCD models like the TI-1768 in Japan. Together with the TI-1020 and its sibbling TI-1015 some more calculators like the TI-15, TI-21 or the TI-501 manufactured in Taiwan were introduced.

TI-1020_PCB.jpg (50931 Byte)The electronic inside the TI-1020 is very unusual for a Texas Instruments calculator - a chip manufactured by competitor Sharp. The designation TI-1020 forces this calculator to the Basic section, actually it features the xn-function not found on some scientific calculators !

Like the TI-1015 two colours appeared, this brown model and a grey one. View it here.
