Petros Kokotis developed a replacement for the ever popular SID chip (MOS Technology 6581/8580) using a Teensy 3.6.
The SID was a popular sound synthesizer chip from the 1980s used in the Commodore 64 computer. Much to the dismay of many nostalgic computer enthusiasts, it hasn’t been manufactured for many years.
Petros used a Teensy 3.6 and some level shifting boards to intercept address and data lines of a SID chip. He also used the Teensy Audio Library and the ReSID Library by Frank Bösing (from his C64 emulation).
Code for the project can be found in this GitHub repository.
