A fairly advanced electronic organizer, the Royal DM80nx provides calculator, time/date, data storage, and personal telephone book functions. It is mostly gray and has a hinged lid with a "Quick Reference Guide" on the inside.
The Royal DM80nx also has a 3-line LCD with a backlight. There's a separate numeric keypad, and the spacebar is larger than the other buttons. On the bottom panel, this organizer has a battery compartment and a small, recessed RESET button.
Basically, this unit combines the capabilities of a calculator, a watch, and a small notebook into one compact device.
