Display from calculator

[the_edge]

Hi, I have display from my old calculator and I wanted to use it for something, dont know what yet... Well the thing is that it has 68pins, and I dont have its pinout, so I wanted to ask if anyone can tell me the best way to check the function of the pins... there is no serial number on dislpay. the calculator model is "porpo YH-2000A" if anyone knows it...


thanks

is the calculator working?
if yes and you do not have the pin for a start try to check the voltages at each pin.
