To get the quotes, you need to get 5 Combat bot boilers and 5 steel plates.
To get the boilers, you need to disable 5 Combat bots and bash them until they break apart. Steel plates can be found in the various storage rooms.
Get to the Rolling machine in Bay A and put in 1 boiler and 1 steel plate then active the machine. Do this for each of the five pairs. After the last pair has been placed and rolled, the scroll containing the developer quotes will appear at the end of the machine.
Easier way to get quotes
Go to your Thief 2 Directory. Enter the RES folder, then find the file "books.crf". Open it using WinZip or another ZIP tool. Inside books.crf, enter the "english" directory and find the file "M16B66.str". Open the file using the Wordpad or any other word editing tool.
Avoid 'No-Kill' Rule
Throw a weapon such as the Mechanist mace, or the Hammerite hammer, to kill enemies but avoiding the no-kill rule at the same time.
Make a save file just before finishing a mission. Complete the mission as usual, and than make another save file in a different save location. Reload the save file that was made before the mission was finish. Complete the mission again. Your money count is now double of what it should be. Repeat this if you choose so.
