Since re-engineering the central hull height after the new world height limit was introduced, we've had a darn-silly "Deck 0" above Deck 1. No longer. I just spent an hour and relabeled all the decks properly. The radar bridge deck is now Deck 1, the airlock deck is Deck 8, and the bottom deck of the central hull is Deck 14.
PhraseExpress was utterly invaluable in re-doing the hundreds of signs on the stairwells and dropshafts. Brilliant little program, that.
In other news, Polpolion recently created a nice Radar Bridge, including redstone wiring to control the radar dish lights.

He did a good job, so go check it out! Pol, if things look slightly different, it's because I went through the next day and sorted out some of the redstone tangles, color-coded the 2 lines where possible, etc. Hope you don't mind!
