Hi, Just looking at the Atomiswave Card Reader on the control panel and wondering how and where it connects to. The short cable on the reader itself is labelled RF but is very short so I'm guessing I'm missing a longer join cable. I can't find a corresponding RF connector in the main floor of...

No. But we have EBay!!! Linear or log pot?

As the title suggests, what value and type of pot should be used as the volume control in an mk1 board? Thanks

Anyone have a 100% working mk1 sound board for sale to go with my y unit main board? Cables not essential. The sound board I currently have is faulty. Thanks guys.

I had a similar cmos problem with my mk2 board. I went through the usual set of checks but it seems leaving the cab on for a few minutes did the trick. http://forums.arcade-museum.com/showthread.php?t=261355

Got the new IC today. Replaced the old one with it. Needless to say it made no difference. Same loud humming or buzzing still there. Think I'm going to have to call time on this sound board.

Thanks brood. Chip ordered and after shipping. Ill update here again once replaced.

Thanks brood. Can pick up one of those amps for under the equivalent of ten dollars shipped. I'm not confident that it will fix my problem but ill give it a go anyway. Call it a day after that and look for a replacement sound board.

Thanks brood. What type of chip is the amp? I'm in Ireland so nght try pick one up locally

Thanks brood. Ill check that again but as I said anyway I tried grounding it with no change :-( How much does an amp cost and where do I buy? So who's selling a sound board!?

Tried grounding pin 3 on p6. No difference. Looking at the underside of p6 on the sound board, both pins 3 and the keyed one beside it don't seem to go anywhere. No traces etc. Not even to ground. Audio amp time?

Hi, A mate of mine has a working Ridge Racer 1 board set. Is it possible through a Rom upgrade to convert it to Ridge Racer 2? How about Rave Racer? Thanks guys

Just to confirm guys. Pin 3 on p6 on my sound board is blank. No pin there. The cable I received has that pin blanked on the Molex connector as well. That sound right?

This board needs -5v. Perhaps your psu doesn't supply this?

Thanks guys. Probable be a couple of days before I get to stick the board in my cab however I will check for continuity between that pin and ground tonight as a start. That should be enough to give me some indication.

Had a look around Tue sound board and all the caps visually look ok. Pics of board and main caps below. Does the fact that I'm getting a loud hum still not mean that the amp is indeed working ok?

Thanks brood. What you mean by can caps. Those big sized ones? I presume. I'm only concerned with components on the sound board. Apologies for the questions, not too familiar with the terminology.

Thanks man zeno. Can you give me any pointers, what I should be looking for etc I wouldn't know where to start.
