Hi, I've been posting my fun over on http://forum.arcadeotaku.com/viewtopic.php?f=4&t=30924&p=427833#p427833.
Is it possible to configure the J-PAC jumpers to do the Hori/Vert Sync-> Composite sync + amp the levels, but to allow 15/24/31kHz with some permutation of the jumpers? It seems I have to choose a single fixed-frequency.
The screen will auto-sync to 15/24/31kHz, but I need a J-PAC. It won't sync to a VGA signal over the DE-15 connector. The J-PAC seems to lock be in to one frequency at a time if I'm understanding the supported permutations (No jumpers = passthrough sync, 15/24/31 individually is that freq, and 15+31 is 15kHz with 31kHz vert sampling).
