A few months ago there was a list of links to classic video game emulators posted. Very recently, I'm pleased to report, those links all came true. The Internet Archive bespoke upon aforementioned consoles, computers, and mileposts on our way to the tech utopia of today, (seriously, where's my flying car?) and they asked us to do something: Imagine every computer that ever existed, literally, in your browser. And it was so. I have absolutely no affiliation with jscott, btw. Thought I should disclose that.
There was a demon that lived in the air. They said whoever challenged him would die. Their controls would freeze up, their planes would buffet wildly, and they would disintegrate. The demon lived at Mach 1 on the meter, seven hundred and fifty miles an hour, where the air could no longer move out of the way. He lived behind a barrier through which they said no man could ever pass. They called it the sound barrier.
