My contribution. I found a txt based version of the Floor 13 manual. Enjoy!

update: I've just read it, and I can see why the game was later sold without it. Simply playing the game tells you all you need to know about it, for the most part.
Concerning the person who asked about raising the intensity of the interogations: From the DG's "door" screen you click for "go to departments". Then click on "Interogations" Then "captives". You will see buttions there for raising the intensity.
level 0 is minimal and is the starting level for all captives. Not exactly "the comfy pillows" or "the comfy chair", but the captive will not die so quickly.
level 1 is ordinary infliction of pain using commonly available items.
level 2 is "scientific" infliction of pain using specialized equipment.
Be aware of the reports of the captive's health as the days go by. If they are not that healthy to start with and you apply level 2 right away, they may die without telling you anything. Conversely, if they are very healthy to start with, it may take to long if you stay with level 0.
Gosh, this game is really really sick! I hope playing for too long doesn't permenantly twist my mind. (But then again, I've been playing Jagged Alliance 1 and 2 for too long). It's really sad how the war on terror has made relevant all the issues this old game raised when it first came out.
