I don't see how would that work? First off, the computer would have to run on Metallic Arts. I don't see how would that work; my model only replaces the data storage, not everything.
My main theory are sentient ships Compounding steel.
We could also use Feruchemical cadmium for storage or even, as Marasi has implemented it, an actual temporal grenade. It would work marveously, especially since it's not harmful by itself; perfect for capturing people, especially in highly populated areas.
