Emp???? Myth or facts

just got done reading One Second After and had some questions regarding the susceptibility of certain items mentioned in the fictional book. I have a hard time believing that ALL the items the book said would go down actually would go down.

My own research doesnt really gel to well w/ what the book said could/would happen.In fact I cant find any referenced sources that fully or even partially agree w/ the book.

Does anybody have any good sources for more info?

Thanks

btw i searched for EMP info on this board and found 0......???????
