It's been 40 years at least since I watched some of them, but here is a partial list:

• The Smurfs
• Transformers
• Thundercats
• GI Joe
• He-Man
• The Flintstones
• The Jetsons
• Scooby Doo
• JEM
• DuckTales
• Gummy Bears

I dont remember if all of these were on Saturday. I remember a show called "Wait till your father gets home" that aired during the week, because it came on right before my father came home.
