Update: I found that I had all the parts so I spent some time with a C16 PCB and replaced the modulator with this circuit. It works, and even though it's a hack job on a 1 inch square of leftover PCB the picture looks better. I assume that the modulator is the same in all 264 systems so the following information should apply to all of them: Modulator pinout: 1 O O 8 2 O O 7 3 O O 6 4 O O 5 1: Sync/Luma out 3: Chroma out 4: Chroma in 8: Sync/Luma in 7: +5V The copper plane the modulator sat on is GND. in = Signal from TED out = Signal to Video output View: Top of PCB, modulator removed, 1 and 8 are farthest from CPU. Video output connector: Chroma : 6 Sync/Luma: 1 TED: Chroma : 13 Sync/Luma: 23 As usual, I'm not responsible for damage to hardware or user if someone tries to use this information and screws up.
