I’m doing a year-long project to reverse engineer the output and functionality of a VIC-20’s video chip, and create a drop-in replacement. At the start of this project (a few days ago), I only actually know how to do a percentage of the things I’ll need to complete this project. Writing a long series on how things work as I learn will help the project along. Plus, maybe having all of this information in one place would be nice, right?
