Hey again all! I am working on getting centipede to play nice with my Jamma test bench. I confirmed RGB wires are properly placed, and have continuity. This harness is outputting to a small control panel, and an Ikegami tm10-17ra via the RGB input. For centipede, I also passed the sync output to both the sync-ext inputs with a small jumper combining them.
This works great for Jamma boards, but I have never tried this with a custom harness.
I also don't know if this centipede works, which is why I built the test harness in the first place
I have the +-5v,+-12v hooked up, but none of the higher voltages that should just be responsible for allowing saving of scores.
Right now, I am just getting flashing vertical lines that are usually yellow, but sometimes are blue and red. They don't shift horizontally, they just flash.
Any idea what I could try next?
Here is a video of it, though it looks way more consistent off-camera.
