ASP-704
this ASP-7 series droid was employed by the Imperial Prefect of Tatooine, shortly before the Battle of Yavin. It was part of a shipment of 200 units, ordered to install communications relays throughout Mos Eisley. The Mark IV Imperial probe droids that patrolled the city regarded the relays as illegal communications systems, and often called stormtroopers to investigate their perfectly legal installation. ASP-704 eventually developed a personality tic, and would strike out at a nearby Mark IV before it could interrupt its work.
