I'm so confused because I'm sure that I'm supposed to take the symbols from the engine and put them in the computer, but I'm not sure if I'm on a Red Herring or if I'm just entering it in wrong.
The connection goes in the other direction. Take a close look at the computer's keyboard, and you'll notice the symbols are more familiar than they might at first seem. Then try to read the symbols on the engine.
I suspect the message on the pole to the far right of the map has something to do with solving the computer, but it's not actually possible to enter it in verbatim (it's both too long and contains a symbol not on the keyboard).
