I'm searching for the 1977 episodes (there were 6) of Laugh In. They are not in the new boxed set. Any help? I've searched everywhere!

I don't have the episodes but I remember watching them when they first appeared on NBC. It was the show viewers got to see for the first time Robin Williams before going on to greater success on Mork & Mindy and movies such as Good Morning Vietnam and Mrs. Doubtfire.
