Short Programs

Select a Project Link below to view each project’s details, including the program code. You can either copy and paste these programs into your favorite Apple II emulator or enter them into your actual Apple II by hand, then type RUN to execute the program.

Programs with the badge will run perfectly fine on a 1MHz Apple II, but may take minutes or hours to execute. For these programs, I strongly recommend using an emulator at full speed or an accelerated Apple II.

Thank you for being one of the like fourteen people who really digs this retro stuff. If you have any problems with the programs in this repo, please let me know by creating an issue. I’m also aware that my one- and two-liners are very hacky and difficult to parse out. If there’s a particular program you’d like to understand better, but you’ve hit a roadblock, let me know and I’ll try to make time to add detailed dev notes.
