Today we look at programming the classic "Hello World" program on the Commodore 64. First we show the trivial BASIC version, and then 6502/6510 Assembly Language, Machine Language, and Machine Code variations in different environments: Turbo Macro Pro v1.2, SuperMON by Jim Butterfield, and a BASIC loader, respectively. To keep it interesting, each environment has a slightly different approach to displaying the Hello World text. No ChatGPT was involved in the making of this video.
