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

Dismantling this TI-35X manufactured in June 1992 reveals a Toshiba T6A58S single-chip calculator circuit mounted on a flexible printed circuit board (Flex-PCB).

A design variation of this calculator changed the colors of the +, -, *, /-keys from blue to grey. Get a picture here.

In the year 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
