Looking for old software - DayMaker v3

I’m trying to recover pre-2000 calendars that were made with DayMaker 3. The developer (Pastel - Hank Williams) is no longer with us and though I thought I had a copy, I only have v1. V1 won’t open v3 files.
Does anyone happen to have an .img of DM3? I’ve searched the usual places (MacRepository, low-end etc.) for orphaned apps, but thus far…
