i have a few armory paper backup wallets.
how do i access the coins in them? i have the root key and chain code.
In Armory just go to the Wallets menu and select "Import or Restore Wallet". Then choose the type you're trying to restore (single-sheet backup I guess). It's all wizard'ified from there.
Edit: Woops, I just realized you were probably talking about accessing the coins without restoring the wallet.
