Wonder no more my friend. They had no time to be bored. They were kept very busy with the operation of the very exotic machine that was an Apollo CSM. They had to monitor the systems that kept them alive, navigate and care for their inertial plateform by regularly sighting on the stars, engaged in scientific experiments, took pictures and much more. The computers couldn't take care of but a few systems, all related to guidance and control. All the other systems like comms, environmental control and power were all managed more or less manually. Also the mission planners made a point of keeping them busy. Each launch was an expensive affair and there was no point in keeping these guys idle. if you want to know more have a look at the Apollo flight journal http://history.nasa.gov/afj/ Very interesting stuff to be learned about these flights.
