In the year 1993 Texas Instruments introduced a new design line that replaced both the TI-68 inspired look of the earlier TI-35X and the boxy design of the TI-30 Stat calculator.
The smooth shape together with rubber-like keys was used on 5 different calculators:
|• 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
• BA Real Estate Financial calculations
Dismantling the TI-35X reveals a novel construction based on a rubber keyboard pressing on a flexible printed circuit board (PCB) with an attached rigid board holding a Toshiba T6A58S single-chip calculator circuit.
Simply by comparing the designation of the integrated circuits of the calculators you'll get the early X-family:
• T6A58 TI-35X
• T6A59 TI-40X Galaxy
• T6A60 TI-9X Galaxy
• T6A61 TI-30X

In the year 1996 this calculator was discontinued. Others like the TI-36X SOLAR survived in a new design. View it here.
