TI-36

Texas Instruments TI-36 is a series of scientific calculators distributed by Texas Instruments. It currently represents the high end model for the TI-30 product lines.

The TI-36 model designation began in 1986 as variant of TI-35 PLUS with solar cells.

It can display 10 digits mantissa with 2 digits exponent, and calculates with 12-digit precision internally.

TI-36 SOLAR was based on 1985 version of TI-35 PLUS, but incorporates solar cells.

It addition to standard features such as trigonometric functions, exponents, logarithms, and intelligent order of operations found in TI-30 and TI-34 series of calculators, it also include base (decimal, hexadecimal, octal, binary) calculations, complex values, statistics. Conversions include polar-rectangular coordinates (P←→R), angles.

Other features include x-y exchange, percentage, register-current stack exchange, factorial, permutation/combination.

Maximum open parenthesis level is 15, with 6 pending operation stacks.

There are 2 operand registers (a, b) and 1 memory register.

TI-35 PLUS uses Toshiba T7767 processor, while TI-36 SOLAR uses Toshiba T7768 processor.

It was manufactured by Taiwanese company Inventec Corporation.

TI-35 PLUS now uses Toshiba T7767S. Cosmetic changes include black shell.

TI-36 SOLAR features smaller, more efficient solar cells, and cosmetic changes. The text "ANYLITE SOLAR" replaces "SCIENTIFIC" on the bottom right of the face.

The design was similar on the 1991 version of TI-68, but without programming features and tilt screen, and only uses 7-segment LCD display. The double shift keys are remained.

Base calculations were updated to include logic operations (NOT, AND, OR, XOR, XNOR). Additional unit conversions include cm-in, litre-US gallon, kg-lb, Celsius-Fahrenheit, gram-ounce. There are 8 physical constants. Register count was increased to 3. New statistic modes include 2-variable statistics with linear regression.

Other new features include cubic root, fraction mode display and conversion (pure/mixed). Complex function was removed.

Stack levels are 15 open parentheses.

TI-35X uses Toshiba T6A58S, while TI-36X SOLAR uses Toshiba T6A57 processor.

It received cosmetic redesigns, which include rubber-like keys and rounder case.

It received cosmetic redesigns, which include recolored keys and labels, rounder case, solid plastic button. The bare processor is now attached directly on motherboard. TI-35 was since then discontinued.
