Jackpot (quest)

The Jackpot: (location) missions are Railroad radiant quest in Fallout 4. P.A.M. wants you to go to various places to collect DIA caches. Each time she gives you a RFID card that will cause the cache to open when you are close enough. The sites are fixed, but the order you will get them in varies.

Quick walkthrough

 * 1) Talk to P.A.M.
 * 2) Find the cache.
 * 3) Return to P.A.M.

Detailed walkthrough
Drummer Boy will tell you that P.A.M. wants something. Talk to P.A.M. and she will explain there are DIA caches hidden around the area, containing all sorts of military-grade gear and supplies that the Railroad is in dire need of. She hands over an RFID card that will reveal these caches. Travel to the indicated location and follow the quest marker to the hidden compartment. There will be enemies. Dispose of them. There is no need to fully clear out the location, as the goal this time is only to reach the cache. When the Sole Survivor gets close enough, the wall section will open up to reveal shelves stocked with various apparel, weapons, ammo and additional aid items. Ransack the cache and leave the area. Return to P.A.M. for a reward.

There are three caches:
 * Hub 360
 * Medford Memorial Hospital
 * Pinnacle Highrise, accessed from the fallen skybridge or a five story high fire escape.

Hub 360
The Jackpot cache can only be reached from the broken buildings on the west side of Hub 360, the top and bottom entrances do not give access to it. Also you can jump from the highway right to that door (location Fallen Skybridge). Another POSSIBLE way to reach it is by using a jet pack through the hatch in the roof of the lower elevator or jumping through the hatch while the elevator is going down from the top floor.

Medford Memorial Hospital
The cache is on the third level. With your back to the entrance of the hospital, it is on the right hand side of the map. The hospital will be overrun with super mutants.

Pinnacle Highrise
Entrance to the ruined skyscraper is just up through the fallen skybridge, or from a fire escape.
