"A heavy metal sphere, which hums quietly."
Tam sometimes has them. Unidentified, they are a small box written in blue for a very insignificant price.
If the player chooses an Alternate Start, the Droid Scrambler, along with the Scratched Disk, can be found on Argyve's corpse in the ruins of Joppa.
If you give this to Argyve as an artifact in Fetch Argyve a Knickknack, it will make the quest unwinnable. He will take every artifact you bring him and never be satisfied.
