Atari 2600 CleanComp (Composite Video Out)
Atari 2600 CleanComp (Composite Video Out)
It’s not new. It’s not fancy. But it is Clean!
We recommend our composite bare wire, S-Video bare wire, or combined lead. On our S-Video cables the green wire is S-Video Y (Luma), and the blue wire is C (Chroma).
Photos in listing are of a photo of a modern TFT playing Pitfall, and then the rest are from a cheap composite capture card to PC to capture images. As you can see even through cheap capture devices the images appear nice and clean.
Version 1.0 Release Notes
This product is still in continued development and the more feedback we receive the more support and improvements we can add. It is at the stage that is should be cleaner and sharper than any other mod out there already, and below are a list of known improvements we are working on for the next version.
1. LUMA0 is still much more delayed than LUMA1/2. Visually you won't notice much of anything, but it does mean I have had to over-dampen the luma to compensate the mixing of the LUMA pins together. This causes slightly softer edges than could be achieved. Plan to fix with a larger LUMA delay circuit.
2. Using switch mode power supplies (instead of transformer based) will introduce 2MHz visual noise all over the image. Not sure if this is normal with RF and other mods, but plan to find a way to filter the system/CleanComp next version. So use high quality/original transformer based power supplies for now.
3. Chroma merges into SYNC rise, causing a slight sync undershoot. This doesn't seem to visually effect anything but I will remove the sync tip undershoot next version with faster transistors.
RetroTink Warning
If you are using a RetroTink some are known to add jailbars and checkerboards to composite and S-Video due to their own PCB adding clock noise to the image.
Use a real monitor/device that supports S-Video, or a OSSC with the composite add-on for perfect results.
