PAM

Predictive Analytic Machine or P.A.M. for short, is an advanced robot first encountered in the Railroad HQ.

Background
First created/programmed in what became known as The Switchboard, P.A.M. started as a military experiment to perform complex modeling for war. She was given a mobile chassis shortly before the war began. While it's unknown what happened to her between when the bombs fell and when the Railroad arrived, it's clear they managed to get her to support their cause in some manner.

Other interactions

 * P.A.M. provides the player character with her own Jackpot missions and occasionally provides information about other Railroad missions.
 * P.A.M. will not talk to the player once the quest Tactical Thinking has started, but will talk again if that quest fails (for example doing The Nuclear Option (Railroad) or The Nuclear Option (Minutemen)).
 * Even after the completion of Tactical Thinking and the total destruction of the Railroad, P.A.M. will still give out some Railroad radiant quests to the player character, such as Variable Removal quests.

Appearances
P.A.M. only appears in Fallout 4.

Bugs

 * Selecting the "Maybe later" response may lead to it not giving any more quests and the player will not be able to speak to it beyond the initial greeting.
 * One can use the console command to fix this.
 * Responding with the "not interested" reply after P.A.M. briefs you about a mission may lead to her constantly being busy and not initiating dialogue, even when you are prompted to speak to it by Drummer Boy.
