Texas Instruments changed in 1996 the design of the scientific calculators to a smoother design. The family covers:
• TI-30Xa Solar
• TI-36X Solar Includes 2-dim statistics, conversions and binary/hexadecimal number bases
Within this family two financial calculators appeared:
|• BA Real Estate
• BA-35 Solar
Together with the new design of the calculators the "chip-on-board" or COB-technology was introduced in the manufacturing process. We know this technolgy 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.
The first generation of the BA Real Estate was introduced already in 1993.
