Need Help with a universal Cab & Naomi Set-up

I finally just got a naomi universal cabinet today that had the naomi system tooken out. I put in my naomi 2 system with gd rom and hooked everything up. Heres the problem. I take it that the universal cab monitor is a vga monitor. When I turn it on everything boots up and I see the naomi logo and everything, but towards the end while botting up, I get a i/o board is not connect to naomi. Do I still need this i/o board in there? There is no jamma harness in the cabinet to plug it into.

The I/O is connected to the USB type connector on the Naomi. If you don't have an I/O present, the system will not work until there is.

So if I have the I/O board connected to the naomi 2 system with the usb what connects into the I/O board? Does anything need to be plugged into the jamma harness part of the I/O board?

As you know, a cable has 2 ends: one that goes into the Naomi and the other side that goes into the I/O. I suppose the questions is, do you have an I/O board? Any Naomi I/O board needs power and it depends on what type you have.

Yes I have the regular Naomi I/O board, not the Capcom one. I thought I tried that also. I had a power harness running to the I/O board and the usb running from the I/O to the Naomi System. I will have to double check everything tomorrow. Thanks for the help. I thought it might have been a setting I needed to change or something. I didn't think I still needed the I/O board in this cabinet.

Post some pictures of the inside of your cab. You said it has no JAMMA loom. Probably has JVS then. Will still need an I/O. The controls are connected to the I/O board.

That is quite a mess, my friend. It's difficult to tell what's going on, but it looks like you have the Jamma JVS I/O. For the sake of testing the system, you don't need the Jamma harness as it will still boot if everything else is connected properly. There are at least 2 power connectors: one for the I/O and one for the GD drive. The problem is, the connectors look exactly the same and yet they are wired differently. One should be shorter and is connected to the I/O. Make sure that you do accidentally switch these connectors or you will burn out either or both parts.
