I think the OP meant, what was the lostech.
Suggestion: Null-Signature Field.
I mean, wouldn't it be great to have Stealth a full decade before anyone else?
ah, makes more sense. I mis-read.
If you throw in something like Null-Sig. You've gotta balance it out by having it extremly hard to operate, keep working and repair. Constant, very high rolls to ensure it stays working would be in stall - not only to ensure it's not too munchkin but also to give it that sense of being "something from another age - the glory days of the Star League".
Or maybe a library, like the Helm core - bascially a library on how to make and operate Null Sig, stealth armor, etc.
Maybe this is where the Cappies later developed their Stealth armor?
