Moppy2
The evolution of the Musical flOPPY controller.
Everything* you need to make your own musical floppy drives!
The wiki has additional information, instructions for getting started, and some other helpful info. If you can't find what you're looking for and have a question or run into trouble and need help just use those links to create a new issue.
Have fun!
* Okay, not everything; you'll need to provide all the hardware.
If you've been here before but you're confused by all the newness, the original MoppyClassic has still been preserved for posterity, but will no longer receive any updates.
