I'm old as fuck so my first computer was one of those Apple computers with the monitor attached, I think they were called Apple II. Those things were bulky and ugly, the screen was monochromatic and only showed green. They even had some games for it and it was pretty fun to play them back then. My favorite was Karateka.
Ok I just googled the specs of those dinosaurs and here they are:
