Like I said in the auction, it works in one Amiga and then doesn't work in the next Amiga. It's a strange card, or I just didn't pay attention to chipset requirements... (maybe it doesn't work with a buster-07 4000?) I didn't spend a whole lot of time trying to nail down what the deal was with this card. When I originally tested it I had 5 different Amigas set up and working besides each other (sold them all on eBay) it worked great in 2 and wasn't seen at all in 3 of them. I was too busy with other hardware to test and get sold so I bagged and shelved this card at the time.
I'm still am unsure why that would be, so I listed it at 99 cents and will let somebody else figure it out.
