Info:In 1981/1982 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. The line covers the TI-1754 (credit card sized), TI-1755 (golden trim), TI-1756 (silver edition of the TI-1755) and TI-1757 (Music Card). All four models got an audible instead of a tactile feedback of the entries.
