From one of the Walkthroughs listed on:
http://dmoz.org/Games/Video_Games/Genres/RPGs/Wizardry_Series/Nemesis/"Now you're in a room with a bunch of pits and walls covered in spikes. One possible sequence is in the Tour Guide. Go to the first pit on the left, jump in, flip switch, climb ladder, sidestep south twice, jump in pit, flip lever, climb north ladder, turn east, jump in pit on right, flip lever, climb north ladder, north one step, jump in pit on right, flip lever, climb east ladder, you're through."
What's so hard about that? LOL
