This demo walks through the logic of the driver program for the homemade MIDI interface that just requires 1 wire connected to Annunciator 0 of an Apple //e or earlier, and 2 pins (+5V, GND) from the back panel game port. It is an excellent project for students to build, test, debug, and expand upon with their own ideas because it integrates electronics, programming, math, and music. So we need to save every Apple //e or earlier we can find from thrift stores, flea markets, basements, etc., and show teenagers how to build this project and help them build their own related projects.
