The PDA syncs with a windows computer, via ActiveSync. After Windows Vista,Microsoft renamed the tool to WMDC (Windows Mobile Device Sync) and it's notsupposed to work on Windows 10, but the community has fixed that by providingpatches and workarounds. I've uploaded the WMDC client with Windows 10patches to Archive.org so you can enjoy it as well. Installation issimple, first install drvupdate-amd64.exe, then WMDC-fixes-for-Win10.msi.Reboot and you should be greeted with the screen below after plugging in thePDA.
