In
most generations of TI calculators you will find a product optimized for
financial/business calculations based on a scientific product. Compare for
example the following pairs:
 | SR-40 and Business Analyst |
| TI-50 and Business Analyst-II |
| TI-55-II and this BA-55 |
The BA-55 could be called a financial calculator with limited programmability, you can store up to 40 keystrokes in the memories. Don't forget one unusual feature of this calculator, you could use the serial printer PC-200 known from the TI-66 PROGRAMMABLE calculator.
The BA-55 was later replaced within the second generation of the slanted line with the BA-54.
