In the year 1982 Texas Instruments introduced not only cheap looking calculators manufactured in Taiwan like the TI-1015 or TI-1006 but some very stylish and thin calculators. 

TI-1755_PCB.jpg (130733 Byte)The line covers the TI-1754 (credit card sized), TI-1755 and TI-1756 (silver edition of the TI-1755). All three models got an audible instead of a tactile feedback of the entries. The design was continued with the later TI-1755 SLR.

The same housing was used with the later TI-1002 / TI-1036 4-function calculator and the TI-1757 II melody calculator.

An even smaller calculator was introduced already in 1979 with the rare TI-1760 DataCard.
