I've seen a few custom DIY JVS IO boards but nothing in the way of consumer level availability. Any links to an alternative solution?

No need for alternatives. The Capcom I/O is a beauty!

Of course! they just cost about the same as the naomi, most I see are around $150 usually more. Figured there was a more cost effective alternative.
 
The SEGA Rev B I/O is cheaper but not by that much. This isn't a cheap hobby.
 
There's the SEGA I/O but it seems to be about the same price these days... sometimes more for a V2
 
The Sega IO is like a third of the price. You just need a JVS compatible PSU.

EDIT: Seriously? That thing too? It was like 30-50 bucks for ages.
 
Yep. It feels like everything except for Golden Tee PCBs have tripled in price...

I know it's not a cheap hobby but that doesn't mean you can't find cost effective solutions or alternatives.

Most times, you can’t, unless it’s a homemade or reproduced product, or you’re willing to sacrifice something for a cheaper price.
 
What are you guys talking about? Sega Rev B's are like $20. They pop up on YAJ all the time.

Avoid the Capcom I/O, its dog shit. it responds to switch requests with the button state at the time of the previous request. Basically it adds input lag, the game will poll inputs and get a response with the state of the buttons at the time of the previous request.

People praise it because it simplifies the Naomi setup, but at its current price you're better off going a different route.

ok so A Sega Rev B IO will suffice for all Naomi 1/2, and Atomiswave? is there anything in particular I need to look out for or any particular model number?
 
If you need the jamma connection, this are your choices basically. These are all described in the AO wiki.
THese ofcourse wont power the Naomi, but your should be running the naomi with its own psu anyway.
The cheapest/most readily available to get would be the Sega ones.

Yep, a Sega Rev B. will work with all Naomi 1/2. Atomiswave is Jamma only, so no JVS I/O will help you there.

I mean to say I'm doing the atomiswave-2-naomi netboot, not running an Atomiswave system. I assume the I/O would work in that case or do I need an alternative for the Naomi?

Correct, that I/O would still work in that case. Any I/O board that works with the Naomi, will work with the the atomiswave conversions. You'd be hard pressed to find a JVS I/O board that doesnt work with Naomi besides those designed for specific applications or maybe some of those Chinese knock off ones which are pretty rare anyway.

What kind of cab are you planning to run the Naomi in?

Currently I'm not putting it in a cab, I don't have the space. I'll be using the HAS and OSSC to interface with it for now.

I'd personally go for the Capcom I/O. It supplies power to the Naomi, has a CPS2 kick harness adapter and takes RCA audio.

I've got that exact setup, I use a Rev. B and picked up a cheap 1U ATX PSU with one of these

ATX-2-Naomi Power Adapters
 
If you need the jamma connection, this are your choices basically.
If you're doing a JAMMA connection you want the Sega JAMMA converter:

This has one of the Sega JAMMA IOs you posted above in it, but it also has an audio amp and a 5V to 3.3V converter just like the Capcom IO. So the only real difference is the kick connector.

The bare-bones Segaa JAMMA IO isn't really meant for JAMMA cabs, it's meant for "JVS Ready" cabs that already have an audio amp and JVS compatible power supply, like the Blast City and New Versus City.

The Sega JAMMA Converter above, and the Capcom JVS IO are really the only two drop-in solutions for running JVS on a JAMMA cab.

it's also worth noting that there is also a cheap Chinese knock-off of the Capcom IO:

note the lack of case, and the black kick connector. I've seen them with and without the power connector populated.
