Season 7 was the final season and only had four episodes. It was changed to a half hour block with one The Real Ghostbusters episode. However, like season 6 the title of the show and intro was still "Slimer! and The Real Ghostbusters". Interestingly towards midway in the season ABC canceled other shows and the real Ghostbusters moved back to the 9/10 slot with a hour show to end the run.
Here is the complete episode listing for Season 7. The rest of the episodes can be found on their pages: Season 1, Season 2, Season 3, Season 4, Season 5 & Season 6.
