Unfortunately the map doesn't exist as you see it as one big image. I pinged Terry about this some time ago. He added all the text and such after it was broken up. The original one piece map is blank, but still may be useful. Download it here:

That being said I started a project some time ago that you may find useful but it got stalled. Been meaning to get the ball rolling again, stay tuned will post on it later today.
