Plus would it effect "generators" ? Way to protect it ? etc....(and what about my pressios comput'z ?) lol
anywho....just looking for how and what it would effect.

Quick n' dirty reply.
EMP will hit in two ways - conductive, and I guess what could be referred to as inductive.
Conductive - [Any] power and antenna inputs will act as 'antennas' and carry the pulse straight into the device.
Unplugging or otherwise electrically decoupling here will help. Pipes, railroad tracks, stuff like that may also conduct the pulse, so don't be
hanging around such thing when it hits.
Inductive is where the electronics of the device are just hit 'directly' by the pulse. The protection from that could in the form of shielding,
like a Faraday cage, or very over-engineered electronics, (but that's a bit more risky).
If you are sat at home / work with your PC on mains power, connected to the phone line, or a LAN, well ... I'd say it'll be toast. A single pulse
is only going to exist for a very short time, so just unplug stuff and put it in a big metal box that is insulated from everything else. Don't
forget to make sure the stuff inside the box is physically insulated from the box itself too tho'.
Generators could well be damaged - anything like electronic ignition could blow, plus any power cables could spike back badly enough to damage the
inverters, or other power components.
There's a bit more
here.
- I'd be far too busy protecting my radio equipment, my power
inverters, some small mains transformers, and a couple of small electronic test meters.
