I'm guessing my G3 issue was a bad cache, luckily I bought 2 G3 266's in the same auction and the second card works. Unfortunately I do have the OS 9.04 upgrade issue now. I do have a flaky 8600 that I might try the upgrade tricck, but all my other machines are G4, whether stock or upgraded. I'm hoping the ATTO card will not be an issue. I also just won an auction for a nubus SampleCell card; so I'm hoping to max the thing out with the ATTO card, ProTools SA4, and SampleCell. The ATTO will allow me to install 1 or 2 extra hi-speed 18 Gig drives. Slowly but surely getting there... Woo-Hooo!
