Ah, Commodore. How I remember thee. My elementary school had a couple of VIC-20s that I always enjoyed messing with.
For some reason that school never understood the notion of uniformity in with computers. Our computer lab had an assortment of Apple ][e, VIC-20, and even one old Texas Instruments TI-90A. When we had time in the computer lab the teacher couldn't instruct us because all the kids were on different computers.
