MAC file conversions

OS = WindowsXP SP1
1 of my users has some old files saved on floppy disk that were created on a MAC using what he thinks would have been Word 5.
When I try to access the Floppy, the PC does not recognise the format and fails to connect to it showing a message to format the disk.
What can I do to make these files available on a windows XP PC
Thanks for some help
