I know the dips are right on the monitor and the naomi. Tested today and 15hz worked and 31hz does nothing. It seems like the screen doesn’t even come on. I tried H. H 30 pot with no luck.
I have two blast city cabs so tried on the other. This one was even worse. I couldn’t get anything to work. Tried dsub 15 and 31 and vga to Capcom I/o so video through the jamma in 15 and 31. None of that did anything. I only flipped dips with the naomi and cab off. Worse still is now I’ve set the 2nd one back to 15hz and tried a jamma board that was working before I started all this and I don’t get a picture.
Ok interesting, flipping the power switch in the back of the cab fixed the issue of no picture on the 2nd cab. Hmmm. I wonder if I should be powering off with that switch instead of the switch in the control panel when I do these tests?
another thing. Powering naomi with the jamma edge through the Capcom I/O did not work for me. Yes I have the proper harness and the naomi turns on and seems ok, but it didn’t work. I’m using a cartridge game so I assumed it would be fine, but now I don’t think so.
