Superprestigio Calafat

The Superprestigio of the eighties at Calafat/Spain (and later at Montmeló) is one of the (few?) internationals that gets ignored by Vincent Glon's fabulous racingmemo site, but I managed to find most race dates and results at the Mundo Deportivo newspaper data base. However, I couldn't find anything on 1981 and '82, and before going through my old magazines in a wild goose chase, maybe someone here knows whether the races took place or not?
