The TI-1030 was the first US-built slimline calculator from Texas Instruments. It used a low-power CMOS integrated circuit manufactured by TI instead the Toshiba circuit in the previous TI-1750. A similar calculator with a more colorful keyboard was introduced with the TI-1070. Don't miss the red E.T.™ calculator.

Manufacturing cost of the slimline models was not too high, the whole calculator uses one flexible printed circuit board (Flex-PCB) with the integrated circuit and a LCD-module. You won't find any hand-soldering or usage of screws within the calculator.

The keyboard is similar to the TI-1200 designs and they suffer all from the same problem of bouncing.

Simply by comparing the designation of the integrated circuits of some calculators you'll get the other members of the slimline LCD calculators and the relation ship between the Basic and Scientific models.
