After some successful repairs, I’m all energized and ready to face my nemesis – the train wreck 3Dfx Voodoo 2. After a failed attempt to repair this badly damaged Creative CT6670 over two years ago, I’m ready to apply what I’ve learned since then to finally get it fixed. Will I be able to get this train back on the tracks? Or will I be defeated yet again?
