If you haven't read it already, here's a knowledge base article on converting old files to FileMaker 11 format: http://help.filemaker.com/app/answers/detail/a_id/750/kw/converting
Given the numerous and drastic changes made to FileMaker, I'd be very suprised to see anything in your file that's useful in FileMaker 11 except for the data itself.
I've not see FileMaker 1 in decades, but check and see if you can export the data as a tab, merge, or csv file. You can then import this file into FileMaker 11 with the new table option. You'll then need to use FileMaker's design tools to craft a layout that effectively displays your imported data.
