This is a very early and completely unsupported version of PsiWin. For customers with Series 3 range machines using Windows XP or 2000 this can be useful as it will sit alongside PsiWin 2.3.3 happily and can be used to convert Series 3 files to PC format. NOTE - This is disk 1 of 3 and you will need to download all 3 to install the application. You will also need to unzip the file to a temporary directory. We would recommend unzipping each disk file into a separate folder Disk1, Disk2, Disk3. Please be aware that Psion no longer provide any support for this application and it is provided here on an 'as-is' basis for those customers who may find it useful.
