"Why," you may ask, "was the internal wiring so insanely packed?" The length of each point-to-point wire was individually calibrated, such that all the signals to each gate arrived at the same moment, so you didn't need flip-flops to latch values in the flow of the circuits. Kind of a "just-in-time delivery" of electrons; and each layer of buffering avoided saved you delay along the pipeline. I don't think this sort of scheme was used on any other mainframe.
