Hi there,
I wonder why a few AC/NAC do have four connectors wired instead of three.
On these pics, the 12 posi fourth connector is wired with several yellow wires (maybe some are +5v since they are yellow). What's their purpose ?
Also, there are some JVS NH connectors and also a blue AMP conn. hooked to this extra harness. Maybe these are for bigger systems like Sega Model 1-3 or others ?
Btw, I guess the cable clamp in the foreground (pink narrow) is only there to hook these extra harnesses ?
