Dual 6581 SID Emulator

Description

This is a weekend project I had in mind for some time now. I used a teensy 3.6 and a couple of level shifting boards to intercept address and data lines of SID Chip.
On software side I used teensy audio library and ReSID by Frank Boesing as a sound engine.
Sound is dual-sid stereo using both dac pins of the teensy.
There are also plans for a led visual equalizer. You can find my source code on my github account.
I would like to thank:
Stephen White the creator of Pi1541 for this guidance and tips on how to proceed with this project.
And my friends at iamretro.gr forum for providing me with enough information of how the chip works and especially users GeoAnas and DAT-ALEX.

Finally after almost a year I uploaded schematics and gerbers to github.
Here is a video of my modded c64 using teensy sid emulator in pseudo stereo mode plus some led eye candy.

This is my homemade pcb of the project. I am going to upload schematics on github in the next couple of days and finished pcb files in a week or so..
