There's something strange about the way the page is coded. I just went there, and everything came up. In the past, I've had to hit the refresh button several times to get all the images to load. Also, I haven't been able to save the page with the diagrams intact, even as separate image files. I finally just had to print the whole thing after I got all the images to load. Then again, I'm using an old computer and software. Try again a little later. If that doesn't work, you might try emailing Steve Ash. His contact info is at his home page of sdash.plus.com.
