Here’s a video about displaying full-motion video on the first IBM PC – “This started as a bit of a joke around the office about doing st00pid things with old technology, like, “Oh yeah? Well, I can calculate fractals on an abacus!” or “Oh yeah? Well, I can surf the web on my Game Boy!”…And one person said, “Oh yeah? Well, I can display video on my XT!”. And later that day I kept thinking about it and came up with a way to do it.” Link.
