This monograph was written from the perspective of the demoscene, i.e. users and creators whose interests are focused on the capabilities of the British 8-bit computer ZX Spectrum. The book does not include the official history of the computer, but the local narrative. The authors examine the processes of taking over the western platform, e.g. mass cloning of the hardware. They investigate creative artifacts specific to the ZX Spectrum scene and discuss the computer's capabilities for creating graphics, music, demos and games, applying the ethnographic method as well as platform studies and media archeology. The ZX Spectrum Demoscene is an initiative of fundamental importance for the study of the history of digital culture in Central Europe. The authors offer insight into the environment, aesthetics and histories of the platform's assimilation in varying social and historical conditions. Dr hab.
