Starting from the very first TI-30 with a red LED-display in the year 1976 all TI-30 variants used an 8-digit display. This is for most calculations convenient but in scientific notation you'll get only 5 digits of mantissa.
The TI-30X introduced a major improvement, the display capacity was eXpanded to a full 10 digit mantissa with two independent digits for the exponent. The complete X-family covered 4 models:
|• 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
the TI-30X 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 T6M38 single-chip calculator circuit.

Later the TI-30Xa added a constant key and all model got a more stylish housing.
The same housing was used with the BA Real Estate.
