Retro computing refers to the use and appreciation of older computer systems, software, and technology from the late 20th century. This includes classic machines like the Apple II, Commodore 64, and IBM PC, which played significant roles in the development of personal computing. Enthusiasts often restore, collect, and use these vintage systems to experience the computing environment of the past. Many retro computing enthusiasts participate in communities that share knowledge, software, and hardware modifications. They may also create or play games from earlier eras, such as those for the Atari 2600 or Nintendo Entertainment System. This movement celebrates the history of technology and its evolution over time.
