I wasn't aware they'd gotten any CPU upgrades working with the Rev.0 G4's, or is it just the very first Rev.0's that wouldn't work? Are there any OS limitations? I might actually be interested if I can run 8.6 (like I'd said, my system is so old it came with the G4 specific version of 8.6). Most likely my only use for the G4/450 is to run some Classic apps once I move to an Intel-based Mac. Either that or for kids gmes. Zane
