The production of the original BA-II was shifted in 1985 from Taiwan to Italy and USA but the overall appearance kept very similar. 

Main difference between the two known BA-II models is the internal construction using a flexible printed circuit board (PCB) instead the rigid type. As a result we notice a slightly shifted position of the display frame and a small reduction in weight of the calculator. 

A similar calculator pair could be found with the
TI-30 III (Taiwan) and TI-35 II (USA and Italy).
