https://tube.loping.net/videos/watch/3a203e11-b733-43ef-aee2-7dfff715eb39 In the 1990s, the Chernobyl Nuclear Power Plant was still operating — but its core control system, SKALA, was a computer designed in the 1970s.Instead of replacing it entirely, engineers built something around it. This system was called DIIS — an auxiliary information-measurement system that connected personal computers to the original SKALA architecture through an industrial bridge computer, the SM-1210. It allowed operators to visualize reactor parameters, run modeling algorithms, and recalculate the reactor’s reference core model locally — while still working with SKALA’s PRIZMA magnetic tapes. In this episode, we examine how 1990s PCs, an ARCnet network, and industrial minicomputers were integrated with a 24-bit Soviet control machine, creating a layered hybrid of three technological eras inside a Chernobyl RBMK unit. This is a small but telling chapter of Chernobyl’s history — showing that the plant did not remain frozen in 1986, but continued evolving quietly in the years that followed.

In our lab, we are building a functional replica of the SKALA controls. Your support helps us preserve and recreate the technological history of Chernobyl — in a way it has never been done before.
