This week I started work on mapping the calculator. I have figured out where most of the keys match with the pins. I am confused though on one column of buttons that I can’t find their pin combo. It is the dead center column. I have found all the buttons to the left and the right but I have not found the combination for them. Is there a chance that they are 4 wires chained together to get them? Like if you press a 2 it is just the one combination as well as the 3 combination?
