ravenxau Posted April 7, 2009 Share Posted April 7, 2009 (edited) Hey gang, While tinkering around this afternoon, i came up with this mod for a 2600 jr (Pal-B) Luma signals through the appropriate resistors, connect the color and sync with wire links and tie them altogether for composite video. While not the best mod by a long shot, it is simple, cheap and gives better results than just tying all the signals together. Give it a try! sync ------------------| color-------------------| Luma1---330ohm----|----------composite video Luma2---100ohm----| Luma0--1000ohm----| TIA pins for Pal-B Jr. :- sync - 2 Luma1 - 5 Luma2 - 6 Luma0 - 7 Color - 9 Edited April 7, 2009 by ravenxau Quote Link to comment Share on other sites More sharing options...
ravenxau Posted April 30, 2011 Author Share Posted April 30, 2011 (edited) Just a small update:- I recently need to mod another Pal Jr. As I was tinkering I noticed that the three resistors (1000, 100, 330) can all be 'scrounged' from the RF Modulator that the mod makes redundant (karma, balance perhaps?).....any way remember to connect the grounds to an appropriate part of the ground rail that runs along the bottom of the board and the 330 resistor is connected to the bottom-left pin of the IC below the RF modulator. join all three resistor lines and the two link line together for composite video. remember the audio is separate. Below is a graphical representation to help you along, Mod Diagram Edited April 30, 2011 by ravenxau Quote Link to comment Share on other sites More sharing options...
