The map at (05,25,11).

This probably has been solved a long time ago, but in the section "Dungeon differences between Atari ST and Amiga versions" you can still read:

"At (05,25,11), the scroll is some sort of map (if someone understands it, please post to the forums):
In the Amiga version, it reads 'Press westward'."

I have not played the Atari-version of CSB for a while, but if I remember correctly:
You have the obvious map directions (N, W, S, E) in the upper left corner, and the other letters is buttons opening specific secret walls. the A-button opens the A-wall and so on. The O and J letters is left to explain.

Oh! Found the explanation (a better one) in a recent post a bit further down. Sorry for my unecessary post.
