The whoe idea of this project, is to make a mini sythn based on this chip, the following is the schematics of all the connections. I used a TTL Crystal Oscillator of 2Mhz to provide the needed clock of the chip, and a 595 to reduce the number of the DATA pins needed for the registry address and data input to generate sounds/envelopes/noise etc.

via Arduino playground – AY38910.
