Mvs jamma?

[Woody8way]

I am a complete newb. Just got a mvs lordsvale. I am going to put a 1 slot mvs in it but not sure if I need a jnx big red adapter? Have I got any other options? Thanks in advance for any advice.

Hi
I think a 1 slot motherboard has a standard jamma pin out. Do you have a picture of the one slot board to confirm ?

If the cab has a game select button, the pinout is slightly different.

Yes my 1 slot is Jamma but I am asking if the harness in the cabinet looks like it used to have a multi slot mvs in it as online it says multi slot jamma connector is different. Hope that makes sense

Thank you. Yes it does.

Yep you'll need an adaptor to std Jamma pinout for a 1-slot MVS board

Thank you. Do you know of any good adapters?

It depends which 1-slot. I have a big OG one and there is a switch to toggle the sound output which converts it from Jamma to MVS wiring
