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.

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.

Find here an excerpt from the Texas Instruments Incorporated leaflet CL-199J dated 1981:

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.

The powerful BA-II brings a new dimension of computing ease to the world of business and finance with built-in functions that let you boil down large sets of data quickly. This powerful 8-digit LCD calculator, with Constant Memory* feature and APD* automatic power down, solves a wide range of time and money problems, complex statistical computations, too. Because it does the math for you in seconds, it frees you to concentrate on "what if" situations and explore financial alternatives.

Quick Facts for Business travels next to your BA-II; gives quick reference for instant financial problem-solving. Its easy “how to” approach shows you the best basic keystrokes you need to make fast, on-the-spot business and personal financial decisions. 

Executive Calculator Guidebook illustrates more than 200 business and personal financial situations and shows how to use the BA-II’s built-in formulas to examine investments, compare money markets, explore lease/buy options, loans, saving accounts and depreciation, project overhead, analyze effects on income and predict trends.
