The olive receiver with pimento activated.
A tiny amplifier built into an olive with a pimento.
When the pimento is pushed one way, it becomes a receiver; when pushed the other way a pimento.
Used by KAOS [Episode #67: "One of Our Olives Is Missing"].
CONTROL later adopts a similar concept as part of the Martini and Olive Radio [Episode #89: "Closely Watched Planes"].
