Texas Instruments
changed in 1996 the design of the scientific calculators
to a smoother design. The family covers:
•
TI-30Xa • 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 |
Together
with the new design of the calculators the "chip-on-board" or COB-technology was
introduced in the manufacturing process. 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.
The first generation of the BA Real Estate was introduced already in 1993.
