OK, so now this gets seriously freaky...
I went back and re-watched "The Ultimate Computer" (TUC) to ensure what I posted above was correct--that the still shot of the
Exeter engineering section sans Kirk and McCoy in "The Omega Glory" (TOG) included the M-5 and was thus lifted from TUC... making it seem like the M-5 was installed aboard the
Exeter too (and maybe even programmed with Tracey's engrams!).
So anyway, I watched TUC, and lo and behold I (initially) concluded I was WRONG. The side of the M-5 was painted white (or light gray), not black like in the image in TOG.
I began figuring what I'd say in my
Mea (7)
Culpa post. But then I discovered the most amazing thing!
In the scene above where poor Ensign Harper (wearing a red shirt, naturally) gets fried while trying to interrupt the M-5's power tap on the warp engines, the side of the M-5 is still white/light gray. Yet, when we see it next, right after the briefing room scene... well lordy lord, the side of the M-5 has turned BLACK!
So I guess I was right after all, but I never realized what an amazing machine the M-5 was... even able to change its own color, sort of like a chameleon. If only my laptop or phone could do that!
