Notes: There is not a lot I can tell you about this calculator for I have no idea at all what all its functions are, except for the scientific functions all the financial functions are beyond me.

The TI BS II seems to have quite a lot of them. More information can be found here on the excellent DATAMATH CALCULATOR MUSEUM: here (link valid 2024-01-13). Apparently this calculator has several pre-programmed spreadsheet like tables that can be used to calculate specific financial problems.

The battery is easily replaceable, it’s behind a small sliding door at the back of the calculator.
