You didn't mention whether you were talking about the DOS or Mac version of the program. Each operating system had a 2.31 version.
If it's DOS, check at your local Family History Center to see if they have the older versions available. I've seen the older Windows versions in FHC's and perhaps you'll get lucky and find the older DOS version.
If you're talking about the Mac version, it's going to be more of a problem, since that equipment is not supported and I doubt you'll find an FHC that has old Macs. Perhaps the poster here can help you:http://boards.rootsweb.com/topics.software.paf/397.1/mb.ashx
