So apparently I've screwed up.
I took a working (I don't know how) Centipede and I've lost audio.
When I got the machine home, I discovered that R29 on the ARII board was blown. I also had some burned pins on the board. I know that this is a common problem.
So I replaced big blue, recapped the AR2 with a kit from ArcadeShop. I also repaired the burned pins on the edge of the board with 1183 tape.
I know that I need to replace the connector, I just haven't gotten to that yet.
So anyways, as I was going through powering up the system, I plugged J8 of the ARII board in while it was powered up. I don't think I had the board plugged in, but I heard a snap.
I get the rest of it going, and now I have no sound.
I currently own a decent digital and analog multi-meters and a logic probe.
Can I use these tools to track down where the problem is?
Can I use the multi-meter on AC mode to track where I have audio signal?
Can I use the logic probe somehow to track it?
I haven't really used the logic probe before so I'm a real rookie on that front.
While I do want and plan to buy a scope, it isn't in the cards at this moment because I blew all my current funds and my wife's patience on a Galaga already this week.
Any help would be appreciated.
Thanks,
Stan
