As I attempted to fix a broken IBM Selectric 3 (from 1976) that I purchased at a thrift store for 20$, I realized that there is a lot of documentation online but not a lot of videos. This is my attempt at remedying that problem.
I ended up learning a lot about how these typewriters work and thought I would share what I learned.
This is not a perfect guide and I am sure I made some errors but it should get you started.
