I have to ask this - while it is super cool to see such an old computer able to be up and running, isn't this a waste of the school's money? Doesn't just running it take an enormous amount of electricity? Wouldn't a $300 PC have about a million times the processing power, and be easier to service and easier for modern users to use? And doesn't it use about 1/1,000th the electricity? Don't get me wrong, I'm glad they still keep this thing running for history's sake, but am a little surprised it's worth the time for a high school to do it.
