A-121 Plotter

The A-121 Plotter was a model of astrogation plotter designed and manufactured by Republic Sienar Systems during the rule of the Galactic Republic. By the time of the Galactic Civil War, modern navigation computers had rendered the A-121 Plotter obsolete. If it was used in an emergency, calculating a hyperspace jump took five times as long and required a jury-rigged personal computer or datapad to download the coordinates into the hyperdrive's motivator.
