TI-34

The TI-34 name is a branding used by Texas Instruments for its mid-range scientific calculators aimed at the educational market. The first TI-34 model was introduced in 1987 as a midpoint between the TI-30 series and the TI-35/TI-36 series. Earlier models included Boolean algebra features, though these were removed with the introduction of the TI-34II in 1999, which focuses more on fractional calculations and other subjects common in middle and high school math and science curricula.

The feature sets were similar to TI-36 SOLAR introduced in 1986, but without complex number support, normal distribution stat functions (P(), Q(), R()), permutations, combinations, factorials, user-accessible operand registers. However, it added fraction mode display and conversion (pure/mixed), boolean logic operations (NOT, AND, OR, XOR, XNOR) over contemporary TI-35 PLUS/36 SOLAR.

It uses Toshiba T7988 processor.

The key and case design was based on contemporary TI-30 SLR, TI-31, TI-32, rather than TI-35/36.

It was manufactured by Inventec Corporation in Taiwan.

It was identical to 1987 model in functionality, except the red keys are now in blue.

It uses smaller solar cell than predecessor. Key colours were changed slightly.

It was manufactured in Malaysia.

The motherboard was smaller compare to the predecessors.

Cosmetic changes include reverting to the key colour scheme used in the 1987 model.

It was manufactured in Italy.

It was manufactured in Malaysia.

Cosmetic changes include rounder case and keys.

It was manufactured in China.

It is a version sold by Stokes Publishing Company, Inc. It is designed for overhead projector use.

It was manufactured in China.

Changes are cosmetic, which uses round keys and different key colours.

It is a version sold by Orbit Research, designed for people with disabilities. It includes speech features. Power source comes from 9V battery instead of solar panel.

It was based on the SR16 design from Kinpo Electronics.

Power sources come from smaller solar cells than the 1994 TI-34, and CR2025 battery.

Feature set was based on TI-36X II, but without unit conversions and constants, base calculations, boolean algebra, complex value functions (abs now only works in real numbers), integral calculation, engineering notation display modes, gradian angle mode, percentage sign, three 2-variable statistic modes (logarithmic, exponent, power), hyperbolic trigonometry.
