Commodore 64 synth chip emulated on an AVR


Because of its classic sounds & serial-controllability, the Commodore 64’s Sound Interface Device (SID) chip is much sought after by many synth DIYers. Instead of plucking one from a vintage piece of computing history, Christoph recreated the SID’s functionality in firmware using an ATMega8 chip. The resulting emulator can be controlled via serial protocol – an Arduino shield was even designed to do just that.
