I think I wasn't very clear in my comment. I think that for things like Word Perfect 5.1, the better solution for longevity would be new open source software that recreates it's functionality in a non-hardware dependent manner. Your mother being able to open Word Perfect files in LibreOffice and print them out with the correct formatting on a modern printer would be easier (and more useful) than relying on the original hardware and software.
