From the 1983 Kenner Toy Fair Catalog:
The Death Star Trash compactor playset recreates several of the key scences that happened on the Death Star in the first movie of the trilogy, the main one being the compactor itself. It also contains Leia's cell block and the computer terminal room where Han and Luke encounter a couple of StormTroopers and acquire their uniforms.
The Death Star Trash Compactor was also included with the Death Star Escape to make up the Death Star World playset.
Some of the features that this playset includes are an elevator, remote blast door that springs shut, and a special hatch that allows the figures to "jump" into the trash compactor.
