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 in the year 1993 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
Nevertheless TI continued the spirit of the TI-30 with the 5 digit mantissa and brought us this TI-30S and its siblings TI-25 SOLAR, TI-25 STAT and TI-25X Solar.
Dismantling this TI-30S manufactured in October 1996 by Nam Tai Electronics, Inc. reveals the Toshiba T6974S single-chip calculator circuit introduced already in 1984 with the TI-30 SLR.
