I'm actually surprised you know about this show. While not extremely rare on Japan since good bunch of people who read/watched it in the 90's remember it pretty fondly (and now more people know about it because the 2010 reboot), it's one of those shows that escape from the western eye. How did you find about it?
As for me, I was just lucky. It was on a recommendation list for children books, since I wanted something simple to read and exercise japanese.
