CyberTech s-Video board and PAL machines

[GamebaseST]

I bought the CyberTech s-video card recently and Atari2600.com were good enough to warn me that I would have to do a few modifications before the board would work with the PAL machine. Basically they list 4 jumper wires that need to be added, along with a socket to allow me to bend the pins out that I need to patch.

 

I successfully installed the board with the jumper wires in place, and I get sound and a picture fine, but the picture is in B&W only. I have tried now with 2x 2600 Woody versions (both had a different version of the PAL TIA chip in), but I get the same result from both.

 

I have checked the continuity of the Chroma and Luma wires in the s-video cable and both are fine, so I can only presume the jumper changes I was given are wrong somehow. I was told to jumper the following:

 

PAL TIA pin 6 -> Cybertech pin 7

PAL TIA pin 7 -> Cybertech pin 8

PAL TIA pin 8 -> Motherboard socket pin 8

PAL TIA pin 12 -> Motherboard socket pin 12

 

I have attached a picture of the modifications, although it is hard to see much in that.

 

I wonder if anyone here has the knowledge of the PAL TIA & Cybertech board to know if the patch instructions above are correct. I'm hoping I can just make a small change to fix this, and soon because I will be exhibiting at this weekends Classic Gamers Expo and had hoped to have this board on display.
