Interesting. It's identical part for part with my Sonnet Tempo ATA133 card. It also has a Promise chip. From the pic I couldn't read the chip part numbers to compare those. For what it's worth my card didn't want to work with a CF card. I didn't experiment a whole lot as I tried a Sonnet ATA66 card and it worked well with a CF in my 9600. It's a very different design.
