Need advice on MVS vs Jamma sound

Hello ,
First i'm a newbie in the arcade stuff.
I just bought a neo 25" candy cab wich is wired for mvs stereo sound.I want to put a taito F3 motherboard in it wich is jamma standard mono.Could you place tell me what i have to do to connect correctly the wire to the speakers and to the jamma harness?

I have a second question about "the coin receptor"(sorry for my english...it's the place where you put the money to have credit in the game).
It seems to be out of order.
I just want to know if i Can replace it with a simple push button?

Thanks a lot

You can see the jamma and mvs pinouts here

http://www.hardmvs.com/manuals/Jamma2NeoGeo4SlotPinout.pdf

MVS is wired 10 to right speaker and L to left speaker (the other side of the speakers are connected to common ground)

JAMMA has one speaker wired between 10 & L on the jamma/mvs edge connect.

Shorting pin 16 to ground will add credits/coin up.

Thanks a lot for your answer ttooddddyy


To be sure everything is clear.
For the speakers i just need to remove the L from the left speaker and connect it with the 10 on the right speaker?
Do i have to do something with "the common ground" (could you please tell me what it is?)

For the credit : connect pin 16 to the ground???sorry but i don't understand......
Can i use a push button to add credit?

Thanks

You simply connect one speaker between 10 and L on the jamma/mvs edge connector. There is no ground connection for the speaker on a jamma cab. There is on the mvs.
Jamma has speaker + and speaker - (the - is not grounded)

Yes a push to make switch that shorts pin 16 to ground will coin up.
