Of course remove the -nospambot from my e-mail address. ********************************************************************* Now the formal things are done. This small project is to provide a simple and easy way to play YM files on a computer using the less possible component. It is currently only using a resistor, a AY-3-3910 (but any version is fine for playing music), a femal audio jack connector to let you ear the nice sound, an Arduino, a buch of wire, and nothing more. Most project I saw before was using a quartz to provide a clock to the AY, but this is just useless and expensive when you have a µC with timers :) As the Arduino does not have enought memory to store the YM file, it is stream from the PC trought the USB virtual serial port. You can find a Fritzing schematic in the file project-ay-3-3910-breadboard.png This project may evolve in a fully autonomous Arduino capable of playing YM/MYM file without the need of a PC. I may use the Gameduino2 for its display and SD connector. More information on this project can be found here: http://www.986-studio.com/category/electronic/ay-3-8910/ ********************************************************************* I've included a simple MYM file with this project: Thrust.mym It's the Title music of the game Thrust on the Atari ST, music composed by Rob Hubbard. To convert ym to mym I recommend the ym2mym tool that come with the OSDK (Oric SDK) that can be found here: http://osdk.defence-force.org Enjoy! Godzil / Manoel
