In the original special effects, the phasers and photon torpedoes magically appeared near the bottom dome. Wow, really high tech. I'm okay with the remastered location of weapon fire (both phaser and photon torpedoes) showing origin in definitely the silver ring round the bottom dome. The ring appears to operate as a phased array phaser and photon torpedo emitter. For "forward, aft, port, midship" phasers, either they are segment portions of phased array ring, or there are more magical emitters on unknown locations around the ship. Possible locations may be associated with the port/starboard running lights (remember the black curved stripes on Pike's E), on the topside edge of the bow, and near the rear dome. The TNG Enterprise-D expanded on this technology with huge phased array phasers, but failed on the torpedo launcher. I dislike the eyeball phaser emitters and Pez dispenser torpedo launchers from the movies, and these retcons to all other designs. Keep the high tech magic.
