TI-30 Scientific Calculator
The TI-30 was a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976. While the original TI-30 left production in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
The original TI-30, a cost-reduced but functionally equivalent version of TI's TI_SR-40 unit, utilized an LED display, was powered by a ubiquitous 9 volt battery, and contained nearly all of its functionality in one chip, where previous calculators used many discrete components. The TI-30 could perform nearly all the logarithmic and trigonometric functions of an HP-21, its primary competition at the time. Although the Texas Instruments SR-50 pioneered algebraic notation with precedence and parentheses in 1974, the TI-30 made those features available at a more affordable price.
