Pip-Boy 3000 Mark IV

The Pip-Boy 3000 Mark IV is a pre-War Personal Information Processor (PIP) in Fallout 4 manufactured by RobCo Industries and acts as a database for the player character's personal information and inventory. It is an updated version of the Pip-Boy 3000.

Reveal
On June 3, 2015, during the Fallout 4 announcement, Bethesda showed a new model of the iconic Pip-Boy in the first Fallout 4 trailer. The new Pip-Boy features several times during the trailer, but is most clearly seen when the Vault 111 resident stops to pet the dog.

Characteristics
The new Pip-Boy features a number of similarities and differences between previous models. It bears closest resemblance to the Pip-Boy 3000. According to the start-up screen, its features include:
 * Pip-OS v7.1.0.8
 * 64k RAM
 * 38,911 bytes of available internal storage

Location
The Pip-Boy is found on the skeletal remains of a Vault 111 scientist right next to the Vault door.

Similarities to Pip-Boy 3000A

 * The 3000 Mark IV Pip-Boy, like the 3000A, is worn on the arm. It features a cylindrical metal case with a large, curved display in the center.
 * The display seems to be defaulted green, like the 3000A model from Fallout 3.
 * The device features a number of rustic dials, a number of buttons below the display that may be used for "mode selection" (similar to the "Stats," "Items," and "Data" buttons of the Pip-Boy 3000). Also featured is what appears to be a Geiger counter and an ambient-orange light.

Differences
There are several major changes to the layout of the device:
 * The majority of the settings dials appear to have been moved to the right of the device so that it can be used easily when worn on the left arm.
 * The new model features two side mounted dials, as opposed to a large "scroll wheel" used in the 3000.
 * The dials used in the new model also resemble cogs, as opposed to the "rocket glider" design used in the the 3000.
 * The primary dial appears to have five settings: Stat, Inv, Data, Map, and Radio, which will replace the three orange-lit buttons in Fallout 3, being used to select a menu the wearer wishes to view.
 * "Radio" is now a main menu, as opposed to it being a sub menu.
 * On the back of the Pip-Boy is a large white adapter plug and cable spool, used to interface with other RobCo-compatible technology, such as Vault door controls.
 * Unlike previous iterations, the Mark IV is not worn with a glove.

Behind the scenes

 * The Pip-boy's start-up screen shows 64 kB of RAM, and 38911 bytes free are a reference to the Commodore 64.
 * A real-world model of this Pip-Boy 3000 Mark IV has been made in limited numbers by Bethesda. It can to hold certain sized smartphones inside and has an app to be used with it when the game is released. It is included in Fallout 4 's Pip-Boy Edition with a display stand.

Bugs

 * Viewing the local map may cause an item in the player's inventory to be displayed in the background.
