Project Cybersyn was a Chilean attempt at real-time computer-controlled planned economy in the years 1970–1973 (during the government of president Salvador Allende). It was essentially a network of telex machines that linked factories with a single computer centre in Santiago, which controlled them using principles of cybernetics.
I think that's quite an interesting cross-over between socialism and computer control.
The wikipedia page has a cool pic of the "control room" which looks totally Star Trek (although other reading suggests that was a prototype control room and not actually used in real life).
