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:
• 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.
