Back in the 80's everybody was playing Atari, Intellivision, or Colecovision. I wanted something completely different and begged my parents for a Commodore Vic 20. I was lucky enough to get one but other than playing games that came in cartridges I had no clue how to operate it at the time. I think I was in the 4th or 5th grade when I was able to write simple commands and make the screen change colors and make funky sounds but other than that there was nothing else it can do that was useful at the time.
