Prototypical Problems

Prototypical Problems is a side quest in Fallout 76.

Background
The Voice of Set is the Mistress of Mystery's iconic gun. To earn it, the Vault Dwellers need to recover data from an experimental weapons research program.

Quick walkthrough

 * Listen to the holotape Order of Mysteries - The Voice of Set.
 * Use Cryptos to access the entry "Novice | Weapons Research."
 * Go to Sugar Grove and access the advanced research terminal.
 * Get the Project Siphon holotape from the analyst's terminal.
 * Return the advance research terminal to download the data onto the holotape.
 * Return to the Riverside Manor and load the holotape in the fabricator terminal
 * Fabricate the Voice of Set.

Detailed walkthrough

 * Cryptos' briefing gives the destination: Sugar Grove, the black site on the other side of the mountains. The goal lies within the facility's SigInt section, namely the research division. After fighting through the robots, the player has to interact with the terminal surrounded by blank holotapes to learn of the EMP weapon project - and the woes of the researcher in the logs, who accidentally filled the entire storage volume with test data.
 * To contain the data without having to lug a mainframe into the Grove, obtain the Project Siphon holotape. To learn about this, they first need to read the last of the researcher's logs, then acquire it from the analyst's terminal. While the waypoint can break, the terminal works as intended. The analyst's terminal is in the corridor leading away from the security checkpoint before the main SigInt chamber: First door on the left. Once accessed, they have to dispense the holotape, then play it on the advanced research terminal to gather the data.
 * Finally, return to the Riverside Manor and play the holotape at the fabricator. Cryptos will make sense of the data and allow them to fabricate the Voice of Set.
