In 1996 Texas Instruments changes the design of the scientific calculators to a smoother design. 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

We know this technology already from the PS-2100 Databank introduced in 1992. The calculator chip is attached direct on the printed circuit board and connected with small bond-wires. A small blob of epoxy resin on top finishes the construction. Don't miss a TI-36X Solar manufactured in China with a completely different internal construction.

The next step in this calculator line is the TI-36X II with a two-line display.

In Germany this calculator survived with a new marketing concept. View the TI-36 eco RS.

Texas Instruments introduced in May 2004 without any announcement the complete redesigned TI-36X SOLAR and gave a first outlook to the impressive design of the BA II PLUS Professional
