I recall using Logo in 3th grade at a Purdue University CS summer camp program. The camp was 1 week long and we stayed in the dorms like real university students - very cool! However, I don't recall any Apple computers. I think it interfaced to a PC using a serial cable. The next year the camp upgraded to Mindstorm kits and we used pbForth instead of the GUI RoboLab. pbForth's author, Ralph Hempel, came down from Canada to teach the camp. It was a true treat! Imagine a bunch of elementary students successfully learning Forth in a week!
