Great easy to use financial calculatore
These are the easiest calculators to do home loans and savings as the entries match the way you think. I have been using them since they came out 40 years ago. Too bad they discontinued them for the more multi function - and more complicated to use - ones.

Great Looking Calculator
I have purchased about six of these types of calculators including the TI 35 Scientific calculator all manufactured in the early to mid 1980s. They are great looking calculators and built very robust but unfortunately over the years the "contacts" between the keys and the calculator itself become "disengaged." Whether the calculator is used or not the keys are unusable and will either not select the number you chose or two or three digits will appear on the screen when you only pushed the key once.

Bad display
I can't answer many questions about it because the display doesn't work properly. Part of the numbers don't appear so I wouldn't be able to say much about it besides that point.

Nice to Find This Old Friend
My battery cover fell off and got lost on my old BA-35. Nice to get the whole thing replaced since the cover replacement wasn't going to happen. It's back functioning on my desktop.

Nice device
Excellent quality, just a bit of pen mark on cover. My device, which I had since the mid-1980's, finally died. It was great to find a replacement.
