Texas Instruments changed in 1996 the design of the scientific calculators to a smoother design and replaced the original TI-30Xa SOLAR. The family covers three members:

TI-30Xa Solar
TI-36X Solar   Includes 2-dim statistics, conversions and binary/hexadecimal number bases

Within this family two financial calculators were introduced:

BA Real Estate
BA-35 Solar

The next step in this calculator line is the TI-30X IIS with a two-line display.

A more robust calculator was available short time in the housing of the TI-32 Explorer Plus as TI-30Xa SE. In 2005 Texas Instruments failed with the TI-30Xa Solar School Edition for Virginia and recalled about 160,000 calculators. Don't miss the TI-30 Xa Solar (H.K.E.A.).

This TI-30 Xa Solar is one of the 6 calculators that were awarded with the Blue Angle environmental label. But Texas Instruments never decorated the calculator with the logo.

In Germany this calculator survived with that marketing concept. View the TI-30 eco RS.
