JVS
From Arcade Otaku Wiki
JAMMA Video Standard or JVS is an updated JAMMA created in the late 90’s. JVS uses an HD-15 type video connection (commonly known as a VGA connector, although VGA is a resolution), Stereo RCA audio connections, JST_VL power connections with 3.3V. Controls are handled via an I/O PCB within the cabinet which connects to the game hardware by an USB cable - it's only the physical cable that's USB, and the signals have nothing in common with USB at all.
