i/o

Does anyone know if the MP07-IONA-US I/O board works I connected to a USB Encoder board. Essentially using a JVS system connected to a usb encoder and then arcade buttons for a mame set up?

I live in Japan so i/o etc should be somewhat easier to get. I would like to know which i/o works. I would also like a wiring diagram, etc. thanks bro

Hi wondering if anyone tried jvs io to usb converter from aliexpress and if yes what was your experience? looks like a decent solution for fair amount of money https://www.aliexpress.com/item/1005004351201540.html
