In the year 1993 Texas Instruments introduced a new design that replaced both the TI-68 look of the earlier TI-36X Solar 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-36X SOLAR 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 T6A57 single-chip calculator circuit.

Simply by comparing the designation of the integrated circuits of the calculators you'll get the early X-family:

	T6A57 TI-36X SOLAR
	T6A58 TI-35X
	T6A59 TI-40X Galaxy
	T6A60 TI-9X Galaxy
	T6A61 TI-30X

In the year 1996 the design of these calculators was changed again. View the updated TI-36X Solar here.
