Threw it up on eBay.

Pulled from my 6500/250, should work in any PowerMac that has factory support for a TV Tuner. The required AV input card is not included (but I have one if you need it).

Trying to get somthing closer to what it's worth 
*ahem* my bad, it's not a PCI card. I just know it works in PCI PowerMac's.
Hey, if it doesn't sell on Ebay re-post it here. I would be interested but I don't do Ebay.
