Anyone have a list of 70's and 80's Public Domain movies (from the Horror/Scifi genres if possible)?

I work on Chiller Theater with Ned The Dead and all of the movies he has are older PD movies (like Horror Express, The Corpse Grinders, The House on Haunted Hill, Plan 9 From Outer Space and Night of the Living Dead) and he is looking for newer 70's and 80's PD movies to show. Looking for everything from Slasher to horror to scifi to fantasy movies from this era in the PD.
