The Organiser II was released in three main guises - CM (8K), XP (16K) and LZ (32K). The LCD display on this XP model allows 2 lines of 16 characters (itself an upgrade from the single line offered by the Organiser I). The display on the CM was the same, but the LZ had a larger offering of 4 lines of 20 characters.

In addition to allowing diary and address book functionality, programs could be written using OPL (Organiser Programming Language).
