Well, I'd start by looking for copies of the original disks from the usual websites.  Macintosh Garden has an extensive catalog.

If Macintosh Garden doesn't have disk images of the original floppies (sometimes they're just Stuffit Archives with all the files already installed), your next step is to ask if anyone else here or at Vintage Forum also has the game, and see if they can send you disk image copies of their floppies.
