Overview
SID DUINO3 is an open-source printed circuit board by keithlegg, from the keithlegg/sidchip_utils repository on GitHub. It is a 2-layer board of 64.8 × 54 mm with 42 parts on 38 nets, routed with 571 tracks and 44 vias.
It is built around the LM7805 and LM7812. Its parts include 11 capacitors, 2 ICs and 2 diodes.

If you ever get the chance to purchase 30 rusty old SID chips from an engineer who worked at Commodore ....
DONT DO IT! Put your energy into something else.
This a small collection of tools, references files, and errata making those old chips sing.
What it is:
siduino - Kicad project / Gerbers A one off PCB design thats an arduino (atmega328p) that has a SID chip on it technically you could program it with the arduino tools if you mapped the pins out properly, but I havent tried it has a 12V and 5V power bus to satisfy the analog-y power needs of the old chips. They run hot.
siduino firmwware - AVR firmware to issue commands to the SID chip from an AtMega328. There is some experimental assembly language driver and some experimental midi in/out.
sidcom - unfinished. A aerial protocol to talk to the SID chip from a modern machine. The board is flawed, the TX/RX pins on the AVR share the lower two bits of the SID chip data bus, so a new board is needed before this can be used. A prototype board is under development.
python tools - Havent done anything yet. The RX/TX flaw really makes this board suck. I need to build a better one with a bigger chip and two SIDs for stereo. maybe someday.
If you are crazy enough to want to build one yourself (beware this revision has the TX/RX flaw):

Questions
How big is the SID DUINO3 PCB?
It measures 64.8 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SID DUINO3 use?
42 parts, built around the LM7805 and LM7812. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SID DUINO3 KiCad files?
From the keithlegg/sidchip_utils repository on GitHub, at the commit this page was made from: the board is siduino/SID_DUINO3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SID DUINO3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask keithlegg before reusing the design.
