Instructions to complete the same demonstration adventure were included in the Gilsoft manuals for the Spectrum, Amstrad, C64, Oric, QL, and BBC versions. The Codewriter demonstration adventure is similar, but different.
The later (1984->) releases of the companion Illustrator tool included a copy of the game database. This was intended to be used with the collection of sample graphics, and the additional tutorial for the tool, to show how graphics and database could be combined into a finished adventure.
In the Spectrum archives there is currently an almost-complete version of the Quill/Illustrator demonstration (minus the additional graphic for the hallway) under the title Dining.

The PC AdventureWriter demo game (also by Gilsoft) was also different, although very much in the same vein.
