Literature on technological decline and related concepts is growing. We aim to advance theorizations of the dynamics of technological decline by mobilizing the concept of sociotechnical configuration and a metaphor of its “unraveling.” We take as a case study the declined Soviet computer series Ural. Ural was once among the top three most used computers in the former Soviet Union, but went into decline and got lost even before the dissolution of the country. We find that technological decline is not a trivial process, it is not guaranteed to be gradual but can feature sudden shifts. These shifts can be drops of production and loss of knowledge, as well as efforts to push back. Policy could make use of ongoing processes of decline and try to replicate the effect of the decline of Ural via cessation of access to materials and competences and delegitimation of the technology.
