It belongs with the sensors designs in this gallery.
From the project
Taiko JVS for Namco System 256
Previously, running Taiko on Namco System 256 required many accessories, such as a JVS (MINI-JV PCB), a SIF PCB, and an intermediate FUTA PCB, making the setup overly complex. This project's PCB can fully replace the three boards mentioned above. It features two independent Taiko interfaces, an onboard Service button, and supports direct power supply via ATX. Alternatively, this PCB can also be used to replace only the SIF PCB and FUTA PCB while still using the original MINI-JV PCB. However, this does not provide a better experience.
