This is the other module I used in my recently ended 1974 rules Dungeons & Dragons campaign. As before, it uses ascending AC.
It was originally going to be based on the Conan story The Tower of the Elephant. However I ended up changing everything except the prisoner Yag-Kosha, and the name of the sorcerer Yara.
The text is here (Word document), and the map is here (jpg). You'll also need the diagram of room 10, which is here.
The idea for the coffee monster (but not the stats) is from the Field Guide to Encounters volume 2. The Men of Wounds are from Varlits and Vermin by Roger SG Sorolla.
EDIT: I've changed the link to the map, in case people were having problems downloading the original link.
