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.

TI-BAII_PCB.jpg (28484 Byte)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 the calculator. 

Simply by comparing the designation of the integrated circuits of the calculators you'll get the first members of the slimline family:

TP0320    (CD3201) TI Investment Analyst 
TP0320    (CD3202) TI-30-II 
TP0321    TI-50
TP0322    TI-Business Analyst-II
TP0323    TI-53
TP0324    TI-35
TP0326    TI-38 and TI-20

In 1984 the era of the slimline calculators was over and Texas Instruments introduced a family of three calculators manufactured in Taiwan:

TI-30 III   
TI-35 II
BA II

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.
