EMP destroys chips whether they are working or not. The EM pulse is of a wavelength that the wires in the chip will pick up like an antenna. These wires often lead to transistor gates, which can be blown out by sudden large voltages. (Transistor gates are very delicate things - comprised of only a few atoms thick layer of SiO2.)

I know a bit more about this on both the risks and defenses, but I'll just shut up due to the nature of the issue...

So pc's, cell phones and anything else with a chip is gone.

Shut up nothing, spill the beans on the defenses.

True, but this only works within a relatively small (but still pretty impressive) radius. For EMP to have a continental effect, the bomb would have to be both very large (or EMP-enhanced) and the EMP would have to propagate through wires.

Energy declines with the cube root of the radius, so no matter how energetic the bomb, you have a hard time moving even a submicron wire two states away.

Fiber telephone circuits were initially part of hardening the telephone network against EMP.
