This is due to the work of archeologist, Jason Scott . Infocom's games are all written in a LISP- like language called ZIL, and the manual 'Learning ZIL' to help understanding is available on the Internet Archive.
The released game is a game that Infocom is good at, and the player instructs the action such as 'go west' to the displayed text. Called 'text adventure' and 'interactive fiction,' Infocomm has developed and released games of this genre from 'Zork' released in 1977 to 'Journey' in 1989.

This genre is basically text-based as the 'text adventure', and although there were games after which images and music were added, Infocom followed the old text-only style.
Infocom merged with Activision in 1986 to become a division, and in 1989 was closed as a division. Gamasutra, a gaming news site, points out that Activision owns Infocom's IP and 'can control' Scott's preservation activities.
