This is a 1-slot NeoGeo MVS board with the game catridge "World Heros". I pulled it out of a mcahine that I MAME'd, so I never tested it (had no interest in an MVS).
Make me an offer, I might consider trade as well. Otherwise this is going on eBay when I get the chance.

**added** Ok, I checked on HardMVS and this board is a model MVS-1. If someone is REALLY interested, I'll make a good package deal on this board and a huge 50" RGB monitor.
