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
 * 38.9 KB (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, & 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.
 * At the back of the Pip-Boy, you can see a device which resembles a vacuum tube.
 * Unlike previous iterations, the Mark IV is not worn with a glove.

Behind the scenes
The start-up screen, 64 kB of RAM, and 38911 bytes free are a reference to the Commodore 64. The Pipboy is able to be used with a phone interface to model a real Pipboy in the preorder exclusive available to ship on the 10th of November 2015.
