Anyone running Naomi hardware in their jamma cab at 15khz?
I assume its as simple as the JVS to Jamma converter and away you go?

I used the Capcom converter when I was running Naomi, very easy to set up.

Thanks a lot guys. Think the Capcom IO might be hard to find and bit pricey a solution.

They are common, usually go for about £150.

Guess its the price then really. Is it any different in performance to the Jamma adapter?

Capcom io converts the power from the jamma edge .. to run the Naomi.
Capcom io offers great simplicity.
It has the power from jamma edge Rather than a sun psu which is nice..
Also has an amp for audio which also is nice.
Also no 5v hook up to power up the io
As with the sega jvs to jamma io.
Having said all that.
If. You have a psu solution for naomi already..
naomi puts sound out the rca anyway.
And a simple 5v / ground conector from the naomi io to the jvs to jamma conector is simple also.
Nothing lost in terms of picture quality
Sound quality.
Controls etc….

Ah that's the issue there. I have no PSU solution. Looks like the Capcom io is what i'll need really. Gonna want to run it in my Astro cab.

I've heard terrible things about Naomi at 480i. Not all bad though, depending on set up.
Dont think the Capcom Adapter will support a NetDimm setup if thats what you are wanting to use, it just cant provide enough power.
Also I seen to remember from the back of my mind that not all games support 15KHz output from the Naomi.
There are also other options, like a Seage JVS to Jamma converter and also one I think was called a Windy and/or River.

No …. You get a normal ATX power supply …
& a ATX to Naomi adaptor …
Total … £ 30 .. job done

I have a good quality ATX supply but my understanding is one of the common reasons for IC's in Naomi boards getting fried is using 3rd party PSU or SUN PSU that need recapping and put out unstable 3.3v?

5v micro usb adaptor for net dimm that’s how I do it

You can monitor the volts with
In line lcd volt meters ( but a good ATX
Crosair etc.. should be better than the older sun psu )
Yes it’s the 3.3v that’s most likely to cause an issue

Like a fast blow 3.5v fuse in line if you can find a 3.5v would be a cool addition
