Old viewfinder push down?
Looking for the name of an old toy and educational product I had when I was a kid. It consisted of a small (maybe 12"x12") moniter / viewer that came with plastic slides that were inserted vertically into the top of the veiwer and pushed down. I think you had to plug it in to work. As the moniter displayed the pictures from a plastic slide like a slide projector, the plastic slide would be extruded from the machine one slide at a time. I remember they had a slide about dinosaurs and one on mixing colors of the spectrum. I don't remember how the naration and sound was recorded. I think it was actually by inserting a small 45 type vinal record at the top. Any ideas?
