You're correct about the auxilliary equipment.
The camera is only part of the complete camera chain. You also need the Camera Control Unit (CCU) for these vintage cameras. Otherwise the camera head is more or less a pretty decoration...
By the way: Far more interesting IMHO are the earlier b/w episodes of Beat Club. Not only due to the lineup, but also due to the fact that the electronic video effects already were used in the b/w era - with black used as the key layer!
