The closest it could get when being adapted into anime was either in the form of commercials for certain products sold in Japan such as toys and snack foods as early as 1980, and a 30-minute animated film produced by Tatsunoko Production which was shown alongside an animated adaptation of Izumi Matsumoto's "Kimagure Orange Road" (another popular "Jump" manga from 1984) produced by Studio Pierrot at a "Shonen Jump Anime Festival" hosted by Shueisha in 1985.
