How to read .pwi file (Windows mobile 5 word)?

Question

Windows Mobile

There are a couple of files with the .pwi extension - notes created in the early 2000s on a Windows Mobile PDA. The PDA is broken, the files are saved on the SD card, but how can I open it now? I was looking for online converters, I did not find it (maybe I was looking badly). Who has had experience, have ideas? Or, perhaps, someone still has a working Windows Mobile 5 PDA?
