I worked for the IT department at the University of Evansville for many years, leaving just three years ago. I've had more than one run-in with this particular site. This site is maintained by hand (no auto-gen) by Dr. Kimberling. He's an extremely smart individual (I've had many classes with him), and he prefers to keep things simple.
Until about 2 year prior to me leaving he kept a secondary computer in his office that was only for running QBasic (an old AMD-K6 running Windows 2K, off the network). He finally gave that up and transitioned to using Mathematica.
