Sweet stuff, let me know if you're looking for someone to buy in as a tester.

How's the sound clarity? Anything done to help eliminate hum/interference?

Sounds great in the vid! very cool!

That echo might sound really sweet on fathom.

I believe at lease these:
Beat the Clock, Centaur, Eight Ball Champ, Eight Ball Deluxe, Eight Ball Deluxe Limited Edition, Elektra, Embryon, Fathom, Fireball II, Flash Gordon, Medusa, Midnight Marauders, Mr. & Mrs. Pac-Man, Rapid Fire, Spectrum, Vector

Sounds great! much cleaner sound, less noise.
Edit:
I should add my original card was re capped / refurbished just about as much as you could do.. This redesigned one kicks serious ass...big improvement!
