“This is not the most original project, but working on my Apple II KSP project got me thinking about ancient sound cards, specifically the Mockingboard Sound available on old Apple IIs. These boards used the AY-3-8910/1/2 sound chips, which can generate 3 channels of square waves with other effects. They were commonly used in some Spectrum and Atari computers, among other places. There is/was quite a scene about generating chiptunes for these chips. So the goal of this project is to have a Raspberry Pi play YM chiptune files onto an actual AY-3-8910 along with some fun LED visualization.”
