CI switched from Roman to Arabic numerals with the latest member of the Construction Master line. Probably--there are Internet reports of a "Construction Master V" that differs from this calculator. The CM5's case folds over the keyboard to protect it, and the battery compartment is shielded with a built-in pocket for the quick reference guide.
