Help identifing this credit/test board

[hatmoose]

Hi Everyone; this credit/test board has popped up on a local auction site for ten bucks.

I'm currently restoring a Namco Excellena (the blue whale) and in need of a credit board, but I dont think it's a match for that.

Does anyone know what this thing is out of? I wonder if it could be (non destructively) adapted to fit? Any and all thoughts gratefully appreciated.

Why do you need a credit board? I have never seen a credit board installed in a candy cab of Japanese origin. It's a Western thing. Admittedly, I have never owned Namco made candy cabs, but I would be extremely surprised be if they had them as stock.

Anyway, you just connect them to power and coin inputs in the cab wiring, so any board can be adapted to work with almost any cab. Very likely you'll have to figure out the pin out of the board on your own though, as there is a ton of these boards, but little to or no documentation.

This story has a sequel;
a year later I was translating the Exceleena manual and discovered that does indeed have a credit board (for weird mahjong games as far as I can tell).
Then I met a man who gave me a complete coin mech and credit board. One chance in a million!

Will document and photograph when I get time.

I actually found credit boards in my Irem Madonnas not long after replying to this thread. I'm not sure what function they serve, because the Asahi Seiko coin mechs are mechanical.

Maybe running a credit counter independent of the game?

Japanese cabs that were repurpoused into specifically BET MJ/hanafuda/8lines/etc had these added iirc
