PAM

The Predictive Analytic Machine or P.A.M. for short, is a sophisticated AI tied to a modified assaultron unit, currently installed at the Railroad HQ in 2287.

Background
The development of the Predictive Analytic Machine abbreviated P.A.M., was green-lighted in 2067, commissioned under the P.A.M. Initiative. This was a joint project between the Defense Intelligence Agency and the military to develop an advanced artificial intelligence program capable of accurately predicting the future, based on data fed into her systems by her human operators. In reality, the primary motive of the people working on P.A.M. was to develop her for foreseeing and stopping a nuclear war before it ever happened. She was eventually wired to a modified assaultron body, granting her increased mobility. This made it easier for P.A.M. to be dismantled and relocated in the event of an enemy attack.

Although the project had suffered numerous setbacks and other misfortunes during the duration of its course, P.A.M. ultimately succeeded in her main goal, managing to correctly predict that Chinese nuclear warheads directed towards the United States would soon be deployed. With this information at hand, the military was able to mobilize its fleet of ballistic missiles and raise the DEFCON status to the highest level in preparation for an upcoming invasion. Although the Great War only lasted two hours, the nuclear exchange had silenced the majority of the larger pockets of human civilization across the globe. Due to its isolated location, the Switchboard never took a direct hit, sparing P.A.M. from the wrath of atomic fire. With her human operators now deceased, the computer's systems went into hibernation, leaving her in a dormant state for over 200 years.

It was only when the Switchboard was discovered by Railroad operatives that P.A.M. would sense the presence of another human after over two centuries of inactivity. The organization's technological experts were able to reprogram the computer to support their cause. P.A.M. would soon prove herself to be an important asset to the success of the Railroad's cause in the Commonwealth.

When the Railroad contingent stationed at the Switchboard was raided by enemy Institute synths led by coursers, having secretly been under the observation of their spies, the survivors of the attack managed to save P.A.M. from being claimed by the Institute. She was recovered from the Switchboard and relocated to the catacombs below the Old North Church fully intact, in part due to her robotic frame. P.A.M.'s advanced mathematical capabilities, processing power and large databases of information about the region ensure that operations are carried out efficiently with little to no chance of failure and that the Railroad remains protected from deadly destruction and annihilation at the hands of the Institute. Because the human race is an extremely complex set of variables, P.A.M. constantly requires herself to revise her algorithms in order to ensure accurate prediction models, especially when wild cards like the Sole Survivor come into play.

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 initiate Railroad radiant quests 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. appears only 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.
 * P.A.M. will sometimes send the player to Far Harbor prior to the start of Far From Home as well as Nuka-world prior to starting All Aboard for a radiant quest.
 * If P.A.M. is reprogrammed and brought back to the Prydwen after the completion of Tactical Thinking, the quest Variable Removal will still be given.
 * One can use the console command to fix this.
 * If Blind Betrayal is completed, she will go into lockdown mode even if the Sole Survivor hasn't talked to Lancer Captain Kells or become an enemy of the Railroad. This makes it impossible to receive or complete quests where P.A.M. must be talked to. This can be fixed by becoming an enemy of the Brotherhood of Steel, but not by having Danse as a companion to temporarily be an enemy of the Brotherhood of Steel.
