I don't remember many of those from the magazine article. I'm sure I hadn't seen the sketch placing the bridge at the back of the neck, in the battle section, which makes sense of a few things (the sketch with the final revisions of the ship overall, with the lengthened nacelles and the bridge added to the top-middle of the saucer, and also that since, if the premise of separating the ship had been stuck with, the stardrive section would've been the half of the ship doing stuff, and it'd make sense for the new, fancy bridge set to stay with it, instead of having the most dramatic moments of episodes in the tiny hacked-up version of the TMP bridge).
