Fallout 76's Wild Appalachia Update, the first major content serving for the title, introduces a number of new quests that players can tackle. One such quest is Wolf in Sheep's Clothing, which sends you to the Garrahan Estate. As you progress through it, you'll be asked to find a Fallout 76 Recall Keycard Circuit Board in order to make an Assaultron Recall Card.
Here's where you can get your hands on the Fallout 76 Recall Keycard Circuit Board.
Fallout 76 Recall Keycard Circuit Board
If you can't quite remember where to find a Fallout 76 Recall Keycard Circuit Board, that's not entirely surprising. The item was added as part of the game's Wild Appalachia Update.
The good news is that, in order to get it, you don't need to arm yourself to the teeth and clear a cave or office building of foes. All you need to do, in fact, is either find Grahm as he roams around or visit Whitespring. A handful of new vendors have settled there, following the update, and some, like the Responders Vendor sells the Fallout 76 Recall Keycard Circuit Board.
Purchasing the Fallout 76 Recall Keycard Circuit Board will set you back 2000 Caps. While parting way with that many caps might not be easy, it does seem to currently be the sole way of progressing through the Wolf in Sheep's Clothing quest.
