Convert 3d files from very old software - Corel Dream 3d

I have about a dozen files from Corel Dream 3d, 1996'ish. I would like them converted into STL or OBJ or some other similar current file. Just the polygons, doesn't need the shaders if they are not available. This would require someone who has an older PC, running Corel Dream 3d, and exporting it to a compatible newer file type. I cannot find any service or utility on the web that handled the format, which is "d3d". I have attached one such file for testing.
