So just finished watching "By Any Other Name" and got some more views of the EMM.
There is a scene where we see Spock and Scotty climb down from the EMM and exit into a corridor which I'm going to guess is the one that runs perpendicular to the Engine Room entrance. However, the ladder I see in the EMM is on the right side which to me would eliminate it going to the corridor and instead go to perhaps the engine room itself. So, I added another ladder and a doorway to the corridor
Hopefully when I get down to the lower level there will be enough room for the deflector control station as seen in "The Enterprise Incident" and "Elaan of Troyius"
