Sound Card for my 286 System

For my sound card, I plan to leverage previous work that I did for my 65816 system build. I will refactor the sound card to support my 286. Along with the sound card itself, I have a series of utilities that allow me to create music note by note, capture MIDI keyboard input, and convert songs in MusicXML format into the format I use for my sound card. For more details on the previous version of the sound card, see these posts:

• Sound Card 2.0 for 65816 PC (maybe a little overboard, but I'm OK with that)
