If you want to unlock Making Friends achievement or trophy in Old World Blues, you will need to reactivate all the Sink’s Robotic Assistants. It’s a “collectible” quest because it is purely dependent on locating the personality chips and installing them in the Think Tank.
These chips will look like holotapes and they will found in several locations around the Big MT. Your quest journal will be divided into several steps towards a set order to retrieve these holotapes.
Starting with the Sink, Auto-Doc and the Biological Research Station. Followed by the Light Switches and Jukebox. Then finally the Toaster, Muggy and Book Chute.
You can pick them all anytime regardless of how your quest journal lists them. Refer to the list below for the locations of where you can find all the holotapes:
