Quick question for SGA fans

The most bizarre Daniel thought process ficlet has leapt into my mind. A quick question, though, to follow it to its proper conclusion: what's the Atlantis equivalent of the DHD? Similar to the "keyboard" on the Gateship from S8? Can anyone direct me to a picture?

I blame this on Zats. She's so much fun to blame things on... :)

edit: Penknife and Zats came through already, yay!
