Here’s a bit of nostalgia from my past! I actually had one of these toys growing up, this must have been around 1978 or so. 2 XL! The robot that would help you learn. It’s essentially just an 8-track player but the makers cleverly placed all the questions and answers expertly on various places on the tape to make it seem like it was intelligent and could interact with you. check it! Scroll down on the page to get to the original 8 tracks which is what I had (produced by Mego), not the later one from the 90s. I can’t remember exactly which cartridges I had but I probably did own at least the superhero and comic book one. Man, this brought back memories.
