Sierra Madre Vending Machine

Sierra Madre vending machines are pre-War devices developed at the Big MT, which dispense and redeem numerous items in exchange for Sierra Madre chips. They can be found throughout the Sierra Madre, and one is found in Elijah's quarters in the abandoned Brotherhood of Steel bunker.

Background
Created at Big MT at the Y-0 research center, the development of the Sierra Madre vending machines was bankrolled by Frederick Sinclair after witnessing them at a World's Fair exhibit. Willing to bankrupt himself for these devices, Sinclair also struck a deal with the company's executives to use the Villa as a proving ground for various Big MT experimental technologies. The devices he commissioned were intended not just as vending machines, but as emergency dispensers supplying food and resources to ration out in the event of a nuclear holocaust. The machines were also capable of outputting special supplies, such as chems and security and maintenance equipment, restricted with dispenser codes issued only to trained professionals and doctors.

Although Sinclair described them as the means for self-sufficiency for the Madre, others felt that they were a means to ensure that any money spent at the casino would line Sinclair's pockets, especially with the ban on all other vending machines. To his employees, the vending machines felt like a company store, as they could barely afford anything with the modest amount of chips they received along with their paycheck.

The Great War and the isolation of the Madre resulted in the vending machines becoming the only known surviving examples of the underlying technology. They remained in the ruins of the Sierra Madre. Around 2281, they attracted the attention of a rogue elder of the Brotherhood of Steel, Elijah. As potentially unlimited sources of "food, supplies, medical assistance, ammo... even currency," Elijah saw that the Sierra Madre "can kill nations and build them" if its Cloud, holograms and vending machines were applied in the correct manner. While the Cloud wipes the slate clean, collars ensure cooperation, holograms provide defense and the vending machines provide everything else.

Principle of operation
While the origin of their technology is unknown, the machines utilize Sierra Madre chips as batteries, while also using the alloys and raw material found within the chips to assemble items. Dispensed items vary for each machine, with emergency items, such as medical supplies and weapon modifications, becoming available after finding vending machine codes. The chips can be easily counterfeited with fission batteries and scrap metal, once the Coin Operator perk has been acquired.

Characteristics
Sierra Madre vending machines initially only offer food, cigarettes, doctor's bags and redeem cigarettes for chips. However, scattered throughout the Sierra Madre are holotapes that enable the vending machines to dispense additional items in quantities only limited by the Courier's supply of chips.

Appearances
The Sierra Madre vending machine appears only in the Fallout: New Vegas add-on Dead Money.

Behind the scenes
The Old World Blues add-on includes an unused, unscripted, partially implemented version of the Sierra Madre vending machine, likely meant to be placed around the Y-0 research center. Called the "Holo-Vending Machine," the object uses the same shape as the vending machines which appear in Dead Money. Though both the mesh (shape) and textures are included for the object, the mesh file references textures as though they are in the "nvdlc01" folder used by Dead Money, rather than the "nvdlc03" folder used by Old World Blues, making it appear incorrectly if viewed without the Dead Money add-on loaded.

Bugs

 * The "Return Outfit Item" vending machine code includes an option to return fedoras for chips. The fedora is a "non-playable" article of clothing, meaning it cannot normally be obtained, and furthermore does not appear anywhere within Dead Money.
 * Returning any pre-War outfit while wearing it will give a permanent Agility bonus. The bonus can be stacked far beyond 10 Agility and though it stops increasing related skills and AP, weapon draw/holster and reload speed will continue to increase. While running some guns may glitch during the holster animation due to the speed of the animation causing the gun to glitch inside the player character, usually leaving the gun sticking out of the Courier's shoulder. The gun will return to normal if drawing and then holstering again while staying still, or if reequipping the weapon.
 * Even though the glitch will increase Agility past 10, the base Agility stat will remain the same in the Pip-Boy due to clothes acting as a temporary increase to SPECIAL, not a permanent increase like an implant.
 * Equipping and unequipping a copy of each returned outfit will remove the stacked agility bonus respective to each outfit return code; e.g. If you have a +4 Agility boost from returning a parkstroller outfit and pre-War casualwear, if you equip and unequip a copy of the pre-War casualwear it will remove the +2 agility provided by that particular outfit, but leave the +2 provided by the parkstroller outfit.
