The OpenJVS project aims to document the JVS (Jamma Video Standard) I/O protocol. This protocol forms the link between an arcade cabinet's logic and its control hardware.

This wiki is used to document the research, hardware and translation of the original specification. The main pages are:

• Protocol -- Main page for all information about the bus protocol
• Hardware -- The hardware we use to interface with the bus
• Samples -- Actual measurements and dumps from the bus
