[Sticky] Adding S-Video to an Atari 800XL
These directions are copied from biosrythm.com which in turn is copied from AtariAge Forums. This is just to help our users find directions quickly on how to mod the 800XL if their unit doesn't support S-Video.
- REMOVE C56 capacitor (if present)
- Lift C54 right-hand side, preferably by inserting an on-off switch (if you want to preserve composite out).
- On the underside of the motherboard, solder chroma-signal wire from R67/R68 junction, to chroma pin in video DIN port pin 5. Follow the cable pathway exactly as shown so the RF shielding fits back on.
- Adjust brightness/contrast/saturation on your monitor. Don’t underestimate this step as I did at first. It’s important and made all the difference in the quality of the final picture.
