Getting back to engine rooms, I've been rethinking the two engine room scenario, one in each hull and both the same design and have a new spin to investigate. Are the Season 1 engine room(s) completely gone in both hulls? All evidence says, yes, they are gone. In the Ultimate Computer (Season 2), there is a very long curved corridor which suggests one is in the saucer. Day of the Dove (Season 3) suggests one is in the secondary hull. On the Exeter, there are clearly two near identical engine rooms. New spin:
Would both rooms have an Emergency Manual Monitor (EMM), or just one and which one? I'm going to look at the transcripts again to see if I can ascertain the activities associated with the EMM. My latest data mine:
All EMM Appearances:
1. S2 Mirror, Mirror (on ISS Enterprise)
- SCOTT: I'll have to tap the power we need from the warp engines and balance it for the four of us.
- SCOTT: We have to lay in the automatic transporter setting, but when we interrupt engine circuits to tie the power increase into the transporter, it'll show up on Sulu's security board.
- SCOTT [OC]: We're ready to bridge power from the engines to the transporter.
- (Scotty does the power transfer from a Jeffries Tube and not in the EMM)
- The EMM has something to do with warp engine power allocation and/or transporter controls. More so with transporter controls.
2. S2 I, Mudd
- Norman runs all over the place including Auxiliary Control, the EMM and the engine room. Net result:
- NORMAN: I am in total control of your ship. I have connected the matter-antimatter pods to the main navigational bank. A trigger relay is now in operation. Any attempts to alter course will result in immediate destruction of this vessel.
SPOCK: Confirmed, Captain. He's taken out all the override controls. If we tamper without knowing where the trigger relay is, we could extinguish ourselves.
- I assume navigation aspects are in Auxiliary Control. Unsure about M/AM pods, maybe done in the engine room. Taking out override warp engine controls sound like something the EMM would be associated with.
3. S2 The Immunity Syndrome
- EMM with huge control console in it.
- SCOTT: We lost five percent of our energy reserve, sir. Our deflector shields are weakened.
- KIRK: Scotty, channel all the impulse and warp power into one massive thrust forward.
- SCOTT [OC]: It's no good, sir. The best we can do is to maintain thrust against the pull and hold our position.
- KIRK: Maintain thrust, Scotty.
- Scotty can monitor energy levels (duh), but mainly, he is actually manually controlling the thrust levels of the engines. Both impulse and warp engines are in use, together.
4. S2 By Any Other Name
- TOMAR: Engineering is secure. (Then he pushes buttons.)
- SPOCK: I've located their power source, captain. It's installed in Engineering.
- (There is a rounded metal object on the console.)
SCOTT: This is it. Now all we have to do
SPOCK: Whatever it is we must do, it is impossible.
SCOTT: Why?
SPOCK: This material surrounding the projector is the same as I discovered on the planet. Readings indicate it is impervious to any of our weapons. We cannot penetrate the casing to get to the machine.
- The Kelvins install a power source that is a power projector machine on the EMM console to help the ship to go faster. The Kelvin's power is added into the ship's power in the EMM.
5. S3 Is There In Truth No Beauty?
6. S3 The Tholian Web (on USS Defiant)
7. S3 The Lights of Zetar
- Captain's log, With us is specialist Lieutenant Mira Romaine. She is on board to supervise the transfer of newly designed equipment directly from the Enterprise to Memory Alpha. (Tools on top of console in EMM.)
- KIRK: As soon as we're within viewing range of Memory Alpha, you and Lieutenant Romaine will go to the emergency manual monitor. You'll prepare for direct transfer of equipment.
- KIRK: Mister Scott, check emergency manual monitor for transporter control.
- This direct transfer sounds like something to do with a delicate or special transporter operation to beam equipment from Enterprise to Memory Alpha, possibly to install it in place in their facilities. There is an EMM for transporter control.
Summary on EMM functions:
- Monitor energy/power levels.
- Allocate power from warp engines.
- Access transporter controls.
- Override warp engine controls.
- Manually control both impulse and warp engines.
- Allocate outside power source to warp engines.
- Access to transporter controls for precision installation of equipment.
- Access to transporter controls for trouble-shooting.
I see two main functions for the EMM. One for warp engine control. One for transporter control. Two EMMs or One? Would transporter circuitry be controlled from the secondary hull? If so, there could be one EMM. If not, then there could be two EMMs, probably one in each hull. One is for warp engine control in the secondary hull, and the other for transporter control in the saucer. Star Trek is rarely easy.
