What would you de-couple? There are no IC packages, all the logic is done with transistors and switching diodes. The fastest frequency in the clock is 60 hz or 16.66 ms. The transistors can readily be biased to switch at moderate speeds and small loads, no high current transients need be generated.
It's a thing of beauty indeed.
