^^ Also, who knows how it will change from concept to production. From what I remember reading, Atlantis was very different from it's initial concept.
Agreed, what we know of now is a basic plot outline and might change significantly when it gets to air. If ever.
So is the sole function of the ninth chevron, to gain access to this automated Ancient ship? And can *any* gate (Pegasus or Milky Way) get there, provided there's enough power, like from a ZPM?
It seems the 9th was a contingency chevron programmed with many functions since its active when orbital gates are used. Except for Mark III Pegasus Gates which actually lack a 9th chevron according to some episodes.
M1 - Regular ground Gate (physical prop, chevrons on front, has 9, only 8 used so far)
M2 - Orbital CGI 1 (double sided, all 9 chevrons always on)
M3 - Orbital CGI 2 (doubled sided, chevrons always on, only has 8)
So I don't know, maybe the 9th doesn't require any more power than an 8 symbol address, but needs a new command code or sequence from a remote device to allow 9. Without it the Gate may just ignore any 9 symbol address.
Atlantis has changed its focus pretty dramatically since Rising
Atlantis has a focus?
