I can’t remember what bizzare series of clicks lead me there, but I just discovered an online copy of the original C-64 manual.  I flipped through it and relived all the emotions of entering and running every single one of the programs in it. I was 10 years old. One of my favorites was the bouncing ball program in Section 4 - Animation on pg. 30.
