Looks like the projectors we had in school. Put the slide in and the image was shown on the wall or big white bed sheet tacked to the wall.
Ours were called opaque projectors I'm sure. research that
This is a small projector has clear slides that I clamp in to it almost seems like a microscope slide
and when you put a specimen on it, let it dry and you can show the entire class at once in an enlarged form.
So what age are we talkin not to be nosy about when you went to school lol
