In 1982 I got a Commodore PET 2001 which my mother rented-to-own when I badly injured a leg and would be immobile for quite awhile. I started playing the games off of the cassettes included with the machine and at some point I typed "List" for the first time. That opened a world that redirected my entire life. I started trying to understand the code and alter the games so I could cheat. Then tried to replicate how the games worked, then made new games, and on and on. The accessibility of that process is rare today. While countless computers have come and gone in the ~40 years since, I still have that PET in my basement.
