So there I was wondering what is something cool I could do with my shiny new panda.
I came up with the idea for a shield to interface two 6581 or 8580 Sound Interface Device chips from a Commodore 64/128 computer. (The ultimate in computer sound chips!!)
I have set myself the following goals, an SPI interface to the FEZ, twin sid chips for stereo output, onboard amplifier chip, dual onboard regulators for the 12v/9v supply to the sid chips so you can mix and match 6581 and 8580 chips, a pic micro with embedded firmware to generate the 1MHz bus clock and provide the 8bit bus without swamping the host processor’s io or resources. And all within the standard shield footprint.
