i think i have a lead.
# The Restaurant at the End of the Universe by Stu Galley
Stu Galley was the Programmer i believe.
Thats a lead, isn't it?
"I started work on the "Restaurant" project after finishing "Moonmist" at Infocom. However, it did not get very far at all. Douglas Adams was working on a Dirk Gently book at the time, so he engaged a friend to collaborate with us. This man was a good writer, but he didn't understand interactive stories very well, and I found it difficult to work with him. After a few months, the project was abandoned, leaving the "Heart of Gold" crew still standing on the surface of Magrathea!"
So if we can contact the programmer, Stu Galley. We should be able to make progress.
