Can the Inventors' cube go on a top-row tech card, or on a card that already has your cube?
Two replies agree on the top-row case; the second-cube case is disputed.

A cube can be placed on a top-row card, but it does nothing, because top-row tech cards cannot be upgraded. Whether the Inventors can put a second cube on a card already holding theirs is disputed in the threads; the civilization card text is the one to check.
