NAMCO SYSTEM 2 Multi

I want to ask a question. Maybe it's a stupid question.
Can namco system 2 display video without installing a video board?

no, it will not function at all without the video board.

thankyou!

By the way, mine also has the finallap3 board. When I received the NS2, it didn't come with an OBJ board. I've been searching for the circuit diagram of the OBJ board, but I couldn't find it anywhere on the internet.
I still don't know the purpose of a black wire. I only know that it connects to pin 6 of the 74377.
