Z-machineThe Z-machine is a virtual machine that was developed by Joel Berez and Marc Blank in 1979 and used by Infocom for its text adventure games. Infocom compiled game code to files containing Z-machine instructions (called story files or Z-code files) and could therefore port its text adventures to a new platform simply by writing a Z-machine implementation for that platform. With the large number of incompatible home computer systems in use at the time, this was an important advantage over using native code or developing a compiler for each system.
ZorkZork is a text-based adventure game first released in 1977 by developers Tim Anderson, Marc Blank, Bruce Daniels, and Dave Lebling for the PDP-10 mainframe computer. The original developers and others, as the company Infocom, expanded and split the game into three titlesZorkI: The Great Underground Empire, ZorkII: The Wizard of Frobozz, and ZorkIII: The Dungeon Masterwhich were released commercially for a range of personal computers beginning in 1980. In Zork, the player explores the abandoned Great Underground Empire in search of treasure.
InfocomInfocom was an American software company based in Cambridge, Massachusetts, that produced numerous works of interactive fiction. They also produced a business application, a relational database called Cornerstone. Infocom was founded on June 22, 1979, by staff and students of Massachusetts Institute of Technology, and lasted as an independent company until 1986, when it was bought by Activision. Activision shut down the Infocom division in 1989, although they released some titles in the 1990s under the Infocom Zork brand.
Interactive fictionInteractive fiction, often abbreviated IF, is software simulating environments in which players use text commands to control characters and influence the environment. Works in this form can be understood as literary narratives, either in the form of interactive narratives or interactive narrations. These works can also be understood as a form of video game, either in the form of an adventure game or role-playing game.
