| Series 1 | psion1 | 4K | The series 1 ROM does not seem to contain a version number, and I do not know if there were different versions or bugfixes. |
This is a collection of pack images from the various software packs that were available for the Psion Organiser 1. These files have the same format as the Series II pack image files, though they have the extension OP1 instead of OPK. Sometimes there is more than one image of a particular pack, but I have not examined what the differences are between those versions, and as there seem to be no version numbers I do not know which image file is better.
