In 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

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
