Texas Instruments changed in 1996 the design of the scientific calculators to a smoother design and replaced the original TI-30Xa. 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
All functions seem to be identical to the predecessors, compare this model from 1996 with the earlier TI-30Xa.
an early TI-30Xa reveals indeed a single-chip calculator circuit manufactured by
Toshiba. Unfortunately the integrated circuit is soldered the wrong way on the
printed circuit board (PCB) and we couldn't get the numbers. Later calculators, make
use of the chip-on-board technology. The PCB on the right was located in a
TI-30Xa manufactured in August 1998 by Nam
Tai Electronics, Inc.

The next step in this calculator line is the TI-30X IIB with a two-line display, nevertheless introduced Texas Instruments in April 2004 a slightly redesigned TI-30XA. The similar TI-36X SOLAR introduced only one month later received a complete new design.
