That's the sound card for Space Fury. Not to long ago a complete Space Fury card cage sold on Ebay for $100.99.Their's 5 cards in the cage so that's $20.20 per board but right now because everyone is looking for one for the new Vector Labs multigame, sky's the limit. I recently paid $55.00 plus shipping for an Eliminator sound board untested off Ebay. I was lucky, it worked. After Vector Labs multi sound board is released the price may or may not drop because they do seem to be hard to find and the people that have them might want to keep them for a back up.
