Arkanoid board and spinner on Astro City?

[Don’s Arcade]

What buttons?

They were leaf switch buttons but I changed them to IL Cherry switch buttons.

Ever since I got the Arkanoid cab the fire buttons/lasers never worked. But the start button obviously worked so I can play the game. It seems like tho the fire buttons are locked in because every time I continue it continues on the same stage where you have to hold on the fire button and press start.

I have a theory now. The cab has a coin button wired on the coin door. I’m wondering if the wiring on this extra coin button is messing with the wiring on the fire buttons.

It sounds like the wiring. I’m wondering if the buttons were wired as “always on”.

I don't think so, but I've been wrong before.

On my F3 arkanid returns the button works like any other arcade push switch.

Logic probes to see if the pin is Hi or lo are dirt cheap. I would start there, could easily tell if it's the harness or board pulling the pin low (most arcade button inputs are active low AFAIK hence common ground wiring. If they were active high the common wire would be +5 and not GND).
