I'm working on a friend's Tayto (yes, Tayto, not Taito) bootleg Arkanoid board/cabinet. The wiring harness is a disaster in it, but I think I've traced out where everything goes. Currently, there is nothing connecting to the coin door from the board. It looks to have been wired for a "free play button" that is currently not connected to anything.
Comparing the wiring I've found to the 22-pin Arkanoid pinouts I've found on the web (there isn't much info out there for this board), I've been able to determine that the "free play button" should connect to pin 8 of the board. My theory is further bolstered by pin 8 on the connector having previous solder on it (yet nothing connected to it currently).
The issue is, when bypassing the wiring rats-nest and just jumpering from pin 8 to ground, I get no coin drop. There are two grounds at the board connection, I've tried jumpering to both. I still get no coin drop.
This leads me to believe there is something wrong with the circuitry of the board (that's fine, I've troubleshot them before). I just don't know where to begin without schematics (as it's a bootleg). Anyone have any tips, maybe common things that go bad on switch inputs of boards? I'm thinking about just starting to trace out the board and see where pin 8 leads me.
Oh, and I know this thing isn't worth the time I put into it, but it's in a rec-room for a charity. They don't have any money to switch out the game, and I'd like to get it going again for the kids.
Let me know if you have any suggestions!
Thanks!
