Within the Majestic series Texas Instruments started with the Business Analyst to introduce always a financial counterpart to the scientific calculator. The Business Analyst-II continued this approach, compare it with the TI-50.
An identical calculator was sold in Europe under the model type TI-44.
Compare this calculator with the TI Investment Analyst and the simpler BA-35 Student Analyst.
Manufacturing cost of the slimline models was not too high,
the whole calculator uses one flexible printed circuit board (Flex-PCB) with the integrated
circuit and a LCD-module. You won't find any soldering or usage of screws within
Simply by comparing the designation of the integrated circuits of the calculators you'll get the first members of the slimline family:
In 1984 the era of the slimline calculators was over and Texas Instruments introduced a family of three calculators manufactured in Taiwan:
It took 8 years before the first TI financial calculator based on a Toshiba calculator chip appeared with the BA-SOLAR. Difficult to understand if you compare this Business Analyst-II with the Canon Financial calculator.
Don't miss the rare Business Card, probably the missing calculator using one of the TP032x chips.
We discovered recently with the Sharp EL-503
a scientific calculator with the TP0327 single-chip calculator circuit, closing
the missing link between the TP0326 located in the TI-38 and the TP0328 known
from the Jeppesen Sanderson avstar.
|TI Business Analyst-II Executive Calculating System
A unique "systems" approach to financial decision-making.
Imagine doing complex calculations to explore alternatives in lease/buy options. Loans, amortizations, real estate mortgages, or sales and earning forecasts in a matter of minutes. Working together as a system, the BA-II,
Executive Calculator Guidebook and Quick Facts for Business give you all this computational capability and much more.
