The
Business Analyst was introduced mid of 1976 together with the entry calculator TI-30
and the SR-40. The technology behind the Business
Analyst was identical to the SR-40 and is described there.
The Business Analyst was the first in a successful line targeting financial calculations. It continued with the facelifted Business Analyst I, the LCD model Business Analyst II and you'll find in each scientific/programmable epoch a financial variant.
The calculator was able to perform 5 different calculation modes:
 | Standar math |
| Annuities |
| Compound interest |
| Profit margin |
| Linear regression |
If you think about the allegory of the SR-40 and TI-30 you'll find it with the Business Analyst and the Money Manager.
Simply by comparing the designation of the integrated circuits of the entry line "Majestic" calculators, you'll get the all members of this family:
| TMC0980 Goulds Pumpulator uses a custom design ROM (CD9801) |
| TMC0981 TI-30 and SR-40 |
| TMC0982 Business Analyst and TI-41 |
| TMC0983 Programmer |
| TMC0984 TI-33 |
Digging deeper into the TMC098x calculator chips you'll locate an OEM-chip used on a TI-30 "clone" manufactured in Hong Kong:
| TMC0985 Amelia Scientific 2001 |
The usage of these modern calculators was easy, Texas Instruments invented with the SR-52 the AOS entry that allowed up to three pending operations within the parantheses.
In Europe this calculator was sold as TI-41.
