I've got a 4 slot that I want to get rid of since I'm ditching my plans for a Neo Geo cab. I'm 95% sure it works (guy I bought it from said it works - I know that doesn't mean much), but I don't have a way to test it out at the moment.
The boards look good, I removed the battery to check for leaking/damage to the area (common problem) and everything is fine there. I'd like to find a KLOVer in the area that could bench test this or hook it up to a jamma cab for me to verify it works, but I likely won't be able to do that until sometime next week. I'd need to find a game to test it with too since I never got to the point of picking any up. Again, I'm confident it works, but obviously I'm can't say I'm 100% sure.
PM me your thoughts on this, if you want pics, etc.
