I'm assuming they run jp30 and the vortex runs the jp20? Not sure which belongs to which, I have some vortexes but there's nothing on the cases that say which one they are.. but I think they're the jp20
I have 2 chassis w screens for retros but they have no mb or ps.. I've got 4 vortexes in various states of disrepair and would like to frankenstein at least one of these retros into a working one.
are the IO boards interchangeable between the two?
sorry for the stupid questions, there ain't a ton of info on these things out there

Someone check me on this but my experience
- retros only run jp30
- vortex can run jp20 and jp30 but wiring harnesses are different, so you can really only hook up the same board it came with originally
- ioboards are not interchangeable due to wiring
Easiest way to identify jp20 vs jp30 is - if the vortex has the ATX power connector it takes jp30

I am not sure about the IOboards. I have a bunch from Vortex and Retro's and they all look the same. But i never paid attention to the connectors so there could be slight differences. I can tell you the metal cage the jp30 fits into is different , meaning you cant use a Retro jp30 metal cage in a Vortex, and a jp30 wont fit in a JP20 metal cage. There was definitely a special metal cage for Vortex jp30.

The IO boards do look the same at a glance, I'm gonna get one of these retros cleaned out and try it out with a couple of different IO boards I have. Appreciate the input

Well one of my vortexes had a jp30 in it but what seemed like a dead screen. It got power but said no video.
Took the jp30 out and it looks pristine.. new heat sink, no dust, etc.
Connected it up to one of the retros that had the most parts in it with itouch 10, connected a few wires up and the thing fired right up
It needed a factory reset, so I did that and it works perfectly, touch screen was perfect, but filthy. Didn't even need calibration.
So of course, I have a question. How in the blue hell do you shoe horn the jp 30 info this thing? The 8 pin cable in the bottom right corner that I'm guessing plugs into the mother's not the daughter board all the rest go into .which I'm assuming is for the side led's isn't long enough to reach very far, .
How is this thing supposed to go? I feel stupid because the cable length dictates what side the thing goes in, but it doesn't seem to fit right.
Anyone have any ideas?

Take a pic of it. Its not a Vortex cage. Nor is it a Retro cage. Might be a good idea to take pics of the wiring harnesses.

will do this evening when I get off work.
It looks identical to the regular L shaped vortex cage, but this one has the atx connector on it and the CF card slot on the backside of the motherboard instead of on the frontside like my other vortexes
edit, after looking at the pics posted above more closely, mine does not resemble the ones in the pics above.. no wonder the damn thing wouldn't fit.
The motherboard is almost exactly the same as the poster above posted with a few small differences it appears, but the cage is the L shaped cage from a vortex.. really odd.
game_nerd:
ok, so here are some pics.. best I can figure is they stuffed a JP30 into a vortex case.. which is no wonder the damn thing wouldn't fit in the retro no matter how I turned it.
The box pictured above is a square one, this one has the shape of the JP20 vortex cases... there are slight differences between my mobo and the one by the poster above, for example the 8 pin on mine is shielded on his and looks to be turned 90 degrees
There's a few cables I left unplugged, I only did the power 4 pin, the atx, the black 5 pin and the white 3 pin.. there is another 5 pin white cable in the retro but it won't fit into this little mobo chassis, which has a 6 pin adapter. The vortex has that 6 pin cable.
There's also a 8 pin white cable in the bottom right corner of the retro, that I think plugs into the white 8 pin plug on the mobo, in the top right corner of the 2nd picture. I haven't plugged that one in and powered it on though, just in case it is not for that. But I think that is the connector for the joystick and buttons if I'm not mistaken. Which cable controls the LED lights on the sides? Those won't turn on even though they're enabled in the settings. I figure one of the cables must power them, but am not sure which one.
