Any1 know how to rig a standard ATX power supply to power a Sega Naomi? I have seen pictures but haven't a clue :dunno or a link where to purchase an adapter :dunno
-
why aren't you using the I/O board to power the Naomi?
-
I don't have the Capcom I/O :'(
-
On my system, the jamma harness connects into the i/o board. The I/o board then connects to the naomi with a usb cable, rca jacks, vga cable and the power connector. I think you need both for the system to work.
-
I have no power connector but I have everything else :(
-
I have a ATX Naomi power cable you can have .

Hold on here. You said you don't have the i/o board, but now you do?
[link deleted because I didn't like how it screwed up the display of messages. If you want to know what I'm talking about, look up "Naomi I/O" on ebay.com. I'm talking about the silver thing in the pics.]
Here's a picture showing the I/O board. Do you have that?
-
You didn't read the post correctly, I said I don't have the Capcom I/O I have the JAMMA one :) you know the low budget one. Now correct me if I am wrong I am still new to the NAOMI the Capcom one allows you to power the NAOMI correct? not the others.
-
To my knowledge, the arcade power supply sends the volts to the I/O board by using the jamma harness. The I/O board then powers the Naomi. *My* naomi system requires the i/o board. If you can show me pics of a "jamma" i/o board, I will be glad to stand corrected.
-
here ya go. :) this is what I have. The person I bought it from said I will need a power supply.

Wow. Interesting. Does it have the VGA/USB/RCA jacks/hookups to it?
-
It has the VGA & USB hookup to it. But I am just gonna run the audio & video str8 outta the motherboard. What I don't know is a) where to plugin the kick harness b) what are the function of the other connectors on the I/O. :dunno Any1 else with a NAOMI that has the el cheapo I/O board feel free to chime in and give me a hand :cheers:

the vga links to vga out of the naomi,this can be set to output either 31khz or 15khz on dil switch position 1 of the naomi mobo
the usb is not usb,its sega adaption

your video can run direct from the mobo as either 15k or 31k but the audio needs to go via an amp

I don't think I need a sound amp. Reason being I have powered speakers in the cab so all I should have to do is adjust volume accordingly. Unless the sound output is equivalent to that of a turntable. In that case a spare reciever I have laying around will do the job.
