I dimly recall talk of the early 'glass cockpit' plans. I'm surprised we didn't end up with dreadful poor quality displays that tended to revert to a little girl with teddy in front of a blackboard! With the relatively poor technology of the time and near total lack of computing power, I assume the displays would have been fed from a 3' camera shooting a brightly lit pilot's panel display in the electronics bay! Like the simulator visual system.
