Do you know if I can legally obtain a copy of this game?

I am desperately searching for a game called Odell Down Under, where you play as a fish in the coral reef and your goal is to find the type of food that your fish can eat and you avoid fish that eat you. Unfortunately, it was originally on a floppy disk, so I am looking to download it—> LEGALLY.
Any help with where I can do that if possible?
