this may have been asked before, but after the bombs fell... how did any pre war electric devices make it through the mass amounts of EMP. i can understand some but, the large amount that is in the games looks o be a little high.

That may have been a bit of an oversight on Beth's part, or more for gameplay's sake over consideration of real world science. In the previous games, working tech was very rare.

i see. ive only played 3 and seen videos of the others.

There's a lot of theories about why so much survived the EMP - I think it's more a suspension of disbelief thing (Fallout has always been "light" science fiction, where the Science only really matters to the extent that it serves what it needs to - I mean nuclear radiation wouldn't realistically give you such homogenized and standard mutations as you see in things like Brahmin, Radroaches, and Giant Ants, for example,) that has more to do with serving the purpose of the gameplay than attempting to be realistic.

On the other hand, in Fallout 2 you see an ad during the opening FMV advertising the Corvega (might be wrong about the name) as a "nuclear war proof" (not an exact quote) car. So presumably there was something of a demand for EMP-proof technology.

I have a theory about the computers you see in the game - sure, we're on an alternate timeline where technology advanced at a different rate - that the working computers you run across in the Wasteland are examples of purposefully simplified and streamlined technology that was designed to last and survive the rigors of the War. That's just something I have fun with, though, and it's absolutely not a "canon" rationalization.

Fallout technology (electronics wise) seems to be based around very advanced vacuum tube technology and basic transistors. One feature of vac tubes is their resistance to EMP.

Under application:

"Vacuum tubes are less susceptible than corresponding solid-state components to the electromagnetic pulse effect of nuclear explosions. This property kept them in use for certain military applications long after transistors had replaced them elsewhere."

I think in great war all bombs were detonated in low altitude. To create EMP you need high altitude detonation, :nuke:
