In some ways, the soviets could take funds from more vanity-projects like hydrofoils and dedicate them to more significant computational research. The soviets in reality had very good sciences with regards to mathematics and by extension the beginning of early software/computer programming logic. Much of cybernetics as a field, despite gaining attention and huge support by the Soviet government under Aksel Berg, ended up squandering its funds in bureaucratic expansion under the cybernetic council with many original scientists involved ending up breaking ties with the field.The Soviets had good ideas for cybernetics, but not computers powerful enough in reality. More investment there and less in the nuclear arsenal?
Otherwise, it is quite well known but little developed in the uchronies, Allende's project for Chile:
Project Cybersyn - Wikipedia

And the Cybersyn is probably one of the closest things we ever got to a socialist cyberntic planning system. It showed promise when some parts of it were first completed before Allende's suicide and overthrow.
I think that many of the early Setun series of trinary computers would actually be hugely beneficial for the soviets to continue in regards to cybernetics, because the trinary system of logic can make up for a lack of Soviet hardware in computational output seen in miniaturised binary computers in the west at that time. And I'm currently writing about this when I get the chance.
