I posted this over on arcade otaku the other day, but thought someone here might happen to have an idea of something to try...
I bought a Taito F3 motherboard (with Bubble Symphony and Bubble Memories), and when I hook the board up to my Sega Astro City (15k), I get sound, but the picture is distorted. The picture is not rolling or anything, though. It's stationary like this:
I tested the F3 board in my supergun (which uses a CGA (15k) to VGA board for the display) and the picture is correct on that, so I know the board works. I also confirmed that the F3 board was receiving the same voltage in my supergun rig and Astro City cab.
I tried jumping pins 1 (ground) and 14 (video ground) on my jamma harness to see if that would get the board to display right in my cab, but no luck.
Thoughts? Suggestions?
