Not much to do here now. Go give the holodisc to Lynette for 1500xp. She'll also send you to Amenities Office to collect your reward. It's a H&K G11, same as the one on Frog Morton. By now you probably have much better weaponry already, but you can always sell it for a few bucks or for ammo. If you sell it, you may want to get the ammo out of it first. About halfway through the Enclave, near the end of the game, you'll find a pretty awesome minigun that runs on 4.7mm ammo.
While you're here, you can go see doctor Troy in the vault again. If
enough time has passed since you brought him the Jet sample, he'll
have discovered an antidote. You can take it to Redding to "Painless"
Doc Johnson for 2500xp (and the warm fuzzy feeling that you cured a
whole city of drugs, and now they're stuck with the ugly post-nuclear
reality :) Then come back here and tell McClure that Troy created an
antidote, and that you delivered it. That's worth another 2500xp.
In case you feel like trying that (I know I did), no, you can't use
the extra antidote bottle to cure Mrs. Bishop in New Reno. Don't
know why, but I kind of felt sorry about that woman :)
Assuming you finished all your business here, you can leave for San
Francisco. If you don't know its location already, just go to the
military base west of Vault 13, then west to the ocean, then north
along the coast. Can't miss it, really.
