BRT-series Computer
this model of super-computer was designed to perform administrative operations on a vast scale, such as managing a huge city or even a small planetary government. Each BRT could manage the activities of 40 million beings, creating and coordinating work assignments and personnel to ensure the smooth, day-to-day operation of an urban environment. In this capacity, the BRT series eliminated the roles of thousands of lesser droids and many humans. This ability scared many politicians and business leaders, who recognized that the BRT was better able to do their own jobs, at a fraction of the cost. In response, these politicians and leaders ordered the BRT line shut down on any number of grounds, and the majority of BRT units was unplugged and physically scrapped. No more than 25 survived at the time of the Battle of Yavin, and most of those had undergone severe memory wipes to reduce their abilities.
