You could search either the Novell site or the Corel site to see if there are any converters available. Novell may still have a utility called CV that converts such files.
Quattro-pro may be able to retrieve the data; although the formating and some features may be lost. (I am not sure about that).
This was a WordPerfect product at one time so WP may be able to import it as a table. But, I have a feeling you would have to find a lower version WP.
If you can find DOS version Lotus 1-2-3, it may be able to import (Again, not sure)
I realize this brings up more questions than answers, but something is better than nothing.
Now, only if hadn't thrown out all those old apps.
