The TI-36X SOLAR is an enhanced version of the original TI-36 SOLAR with a styling similar to the TI-68 calculator. The TI-35X introduced in the same year lacked the solar cells.

TI-36XSolar_3_PCB.jpg (74958 Byte)Dismantling the TI-36X SOLAR reveals no big surprises. We know similar constructions from e.g. the TI-31 SOLAR introduced in 1988.

A design variation of this calculator changed the colors of the +, -, *, /-keys from blue to grey. Don't miss the second TI-36X SOLAR.

In 1993 this successful calculator was discontinued. Texas Instruments introduced a complete new family in a smoother housing:

TI-30X  New display with 10 + 2 digits, 3 memories
TI-30X SOLAR With Anylite solar-cells
TI-35X  Adds 2-dim statistics and hex-calculations
TI-36X SOLAR  With Anylite solar-cells
