 ### Recepticles 9/1/x
 
+Most recepticles work in conjunction with the quest items (8/7/x). With the exception of antenna relay panels, they contain regular actions as data.
+Unless noted otherwise below, the conditions for recepticles are based on object types.

+
+The two ```trigger object index``` values work only with trigger objects, they can't trigger arbitrary objects.
+
+> Behaviour of relays is hardcoded: After accepting the plastique, their type changes to 9/1/4 and a level timer is started. When the timer expires, the panel explodes, the type changes again to 9/1/5, the two objects are triggered and the object-to-destroy is removed.

+#### Retinal ID Scanner 9/1/6
+
+If the condition field is all zero, the scanner triggers its action when activated with any head item (hacker's eyes are never accepted).
+
+> Although the game uses a condition of ```06 00 00 00```, it does not work as a game variable check nor does it match up with the requested head. So far it is unknown how the scanner is bound to the right head.
