A Curious Observatory

[whitbear8]

I so didn't want to ask this, but after a week of frustration and hair loss (I may have pulled a few strands out) I have to do it.

How on earth do you know in  what order to pull the levers in room 31905????

I also desperately need help with this room, finally got past the zappers and got back with a 3rd blue key but only 2 lives left...please help. I don't mind a spoiler at this point, please pm me if needed.

thx.

The large rectangular billboards scattered around give you a code. They flash a number and a letter. Write down the info and solve the code. If you need more help, post again or pm me.
