According to Wickipedia it had a radioisotope thermo-electric power supply that was expected to decay to 200W by the time it got to Pluto. The transmit data rate was expected to be 38 kbit/s at Jupiter; at Pluto’s distance, a rate of approximately 1 kbit/s was expected. The memory was 8gb and was probably used as the storage of images with much less left for software.

My Dad led the project at GE that developed the Radioisotope Thermal Generators (RTG) on the Voyager spacecraft. I remember seeing some amazing development videos he had and he had great stories to tell about the program. See Voyager Spacecraft Radioisotope Thermoelectric Generators.

The Voyager spacecraft have left the solar system. The most recent news was from December 1, 2017: Voyager 1 Fires Up Thrusters After 37 Years
