Koenig's office has it's own wall screen, usually showing a version of the schematic shown on the Main Mission Big Screen.

The normal wall screen display. It is almost the same as the image on the Main Mission Big Screen, but there are small differences (the Main Mission Big Screen has a pink rectangle around the 8 o'clock position that is missing here). The Command Center Big Screen has more major differences.
This wall screen almost always shows a test card design, but is used occasionally as here in Breakaway (other episodes include in Another Time, Another Place).
In Another Time, Another Place the screen is used again.
It is also in the Flight Control room (with a different lower panel), Koenig's quarters (Breakaway only), Bergman's quarters (LQ12) (Matter Of Life And Death, Black Sun, Ring Around The Moon) and Nuclear generating area 3 (again, with a different lower panel).
