We wrote the year 1982 when Texas Instruments discovered the lower labour costs of Taiwan, R.O.C. compared to US or Europe. 

TI-15_PCB.jpg (84016 Byte)Up to 1982 most calculators of Texas Instruments were produced either in US or Italy and some early LCD models like the TI-25 in Japan. Together with the TI-21 some more calculators like the TI-15, TI-18 or the TI-1100 manufactured in Taiwan were introduced. In comparison with the US-built calculators of that era like the late slimline model TI-30-II or the early slanted model TI-55-II the first Taiwan-built calculators look and feel cheaper. But this was only the beginning, a lot of things changed in Taiwan. Ten years later wonderful calculators like the TI-85 were assembled in Taiwan and the cheaper models either in Thailand or nowadays in China.

The designation TI-15 forces this calculator to the Scientific section, actually it features lacks the xn-function found on the TI-1020 basic calculator !
