Overview
Atari2600-SECAM2RGB is an open-source printed circuit board by f1ac0, from the f1ac0/Atari2600 repository on GitHub. It is a 2-layer board of 20.3 × 24.1 mm with 33 parts on 20 nets, routed with 75 tracks and 4 vias.
It is built around the 74HCT08D. Its parts include 8 resistors, 2 capacitors, 1 IC and 1 diode. It belongs with the retro computing and games boards of this library.
Main components
1README
README.mdAtari2600
Inside the lot I bought to get my first C64 was also and Atari 2600. It was also listed as "Untested", and it was obviously salvaged from a flood considering the mud and rust that was inside the case. It came without any game or accessory.
While waiting for the system to dry after a complete clean and rust removal I found the useful projects below to help me start with this system I didn't know anything about.
- First I needed some game so I put together a ROM cartridge on a breadboard and created a PCB from it.
- Then not a single TV receiver I had could tune the video and audio signals correctly, but a BT848 PCTV PCI card. The mod by Eddy Foucault worked perfectly, I made my own version with CMS components and 5v only.
- At last I removed the regulator to power the console from a modern 5V power source.
In this repository are the PCBs I created or modified for my own needs.

Questions
How big is the Atari2600-SECAM2RGB PCB?
It measures 20.3 × 24.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atari2600-SECAM2RGB use?
33 parts, built around the 74HCT08D. 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 Atari2600-SECAM2RGB KiCad files?
From the f1ac0/Atari2600 repository on GitHub, at the commit this page was made from: the board is Atari2600-SECAM2RGB/Atari2600-SECAM2RGB.kicad_pcb and its schematic Atari2600-Cartridge-27C512/Atari2600-Cartridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atari2600-SECAM2RGB design in my own project?
Its repository states no licence, so its author keeps all rights: ask f1ac0 before reusing the design.
