Maybe one of the ROM chips is not working as it should. It would be good if there was an emulator where you could replace one of the ROM chips, for example, with zeros and see what happens.

Unfortunately, ROM chips in the calculator are chipselected by a digital code rather than a CS signal, and it's hard to understand which one is not working.
