Exploring Hard SF Tactics in Space Combat

[Drakkith]

You said that i shouldn't view EMP as anti-electronic placenta.

I think you mean panacea.

But is there any way of more effective electronic countermeasure, that requires only minor magitech?

Sure, there are innumerable solutions that require only a little bit of "handwaving". Just be creative.

I read somewhere that cosmic rays can affect electronics, turn over a single bit could crash a program. While there are countermeasures for it, but if multiple Cpus programs have to check each other, than robots would be hindered.

Maybe not if they're designed to operate with these CPU's and check-programs running. Or if they have redundant systems and can't be taken out because a single bit was flipped on one of their systems.
