[SG] EMP

I just read through a long thread about EMP and the affect on
starships.  My real assumption would be "not much" but that's
neither here nor there.

My real question is what would the affects of EMP be in SG?

Initially I would say:

All communications gear down.  Anything with an antenna
(some missiles?) down.

What about these heavily electronic gizmo rifles?  Can you
still fire one if the HUD is broken?
