Help on remembering vintage toy?

Okay I had this old electronic educational toy and my description is very vague. It was from somewhere in the 80's or 90's and we got it at an old garage sale so I don't know the name of it or anything (and it's been gone for a long time.) I remember you inserted cards or slides and then the actual machine had buttons that you pressed on it. I specifically remember one slide being a family tree of aliens and their names and connections to each other. I believe there were also slides about the solar system, presidents and globe although I could be mistaken about those.

I think it looked and worked a little like a Vtech World Wizard Traveller, but it wasn't that since the alien game was definitely a slide. http://www.amazon.com/VTech-Vtech-World-Wizard-Tra...

Thank you so much! ANY help and ANY suggestions would be so helpful! I spent the last hour just trying to figure this out! Please help!
