Ow guys, please stop yelling - pinsiders are not deaf!

Apart from the new dead world ring, you'll need software that actually works with it. The ring alone is useless as the ball would just keep rotating

IMHO, the best buy is the ring + software kit from Pinbits. They have it in different colors, choose the one you like. I have the orange one and it looks great!

As for the eagle. You could take it off It's only a coupe of screws. Pity it won't fit though, it looks pretty cool!

You get the software along with the ring. It's on an eeprom. You simply replace the current game eeprom with this one. Be careful when switching eeproms - the legs are easily bent! Take a flathead screwdriver and lift up one side of the eeprom, then the other - little by little until it pops out. Then gently push in the new eeprom.

Good luck!
