It seems it worked in some way:
The programme was initially viewed with traditionalist scepticism by Allende’s Socialist Party. But Project Cybersyn’s hour arrived in October 1972 during a strike of 40,000 truck drivers led by the hard-right Confederación Nacional del Transporte. As Allende’s opponents sought to wreck the economy by preventing the transport of food and raw materials, Cybersyn was deployed to underwrite the resistance. Through the electronic network, the government was able to coordinate deliveries by active trucks and to evade blockades. “We felt that we were in the centre of the universe,” Espejo remarked.
After 24 days, the strike was defeated. Ministers then became “much more interested” in Cybersyn, Espejo told me. Allende even proposed transferring the operations room to La Moneda, the presidential palace.
On 10 September 1973, the government finally prepared to install an upgraded version of the system. But the following day, with the connivance of the CIA, Pinochet’s forces stormed the palace and bombed it from the air
