Hi! I have a triple boot of OS 9, OS X Puma, and Debian Linux with FVWM installed as well on my Indigo. I have a restore disk of Tiger for a G4 Mac Mini, and I had no problems using a 800 MHz (I'm pretty sure) iMac G4 install disk for Puma on my Clamshell. It was laggy and I've heard that it has become more efficient. Panther just costs so much I'm not sure I want to buy it, though. Would it make up for my lack of RAM? I think I might upgrade the RAM after getting a new battery. Mine's a FireWire so I'm pretty sure it was supported, and I would just disable DashBoard and SpotLight. Which would boost functionality the most for the least money? I would otherwise be fine with deleting my OS 9 partition, but the previous user left Office on it, which I never had before. I do have enough disk space, so that wouldn't be an issue.
