My fave bit of Voyager trivia:
The speed of the Deep Space network used to communicate with Voyager has quite limited, in part due to the low power of the Voyager transmitters and the enormous distances involved. High resolution photographs could not be transmitted back to earth in real-time, they had to be buffered on-board and transmitted later. The on-board mass storage was achieved with a digital tape drive. You can read about that here:

The cameras were monochrome, so to take a colour image required three exposures, each with a different colour filter. In between Jupiter and Saturn, the software used to manage the digital photography was completely re-written and uploaded to to the spacecraft [just thinking about that process breaks me out in a cold sweat].
One of the issues the imaging software had to deal with was that due to the length of exposures required, and the speed of the spacecraft, the whole spacecraft had to be rotated using its thrusters in order to avoid smearing the image [the cameras were not independently steerable] - while doing this they had to take into account the torque generated by the operation of the digital tape drive.
