The contents of this republished manual were salvaged from the Archived PSION2.ORG website created by Dave Woolnough and maintained by Jaap Scherphuis and Boris Cornet (RIP). It was compiled from various sources to give a complete description of how the operating system and hardware work together. It covers all base models - CM, XP, LZ - and their POS variants. The intended audience are machine code programmers and hardware developers. If you are looking for general information, see the manuals page first!

The PSION Organiser II XP power PCB schematic from page 45 of the manual, drawn by an Organiser II forum member, is for guidance only, it may contain errors and there were at least 3 different boards issued. The most up to date higher resolution copy of the schematic can be sourced from the authors GitHub repository (here).

For completeness the ZIP archive here - salvaged by Martin Guthrie - from the Dolphin Maritime Software Archive July 2023 - holds a copy of Psion's CM/XP Technical Reference Manual.
