Hi, My G4 tower came with 256MB and I gave it another 128MB at the shop. It came with OSX. It seemed to run fine (I think - it did have some kernel panics which Apple said were prolly the fault of bad RAM). I recently added Jaguar and another 512MB of RAM and things run really well. I'd like to put Jaguar on my laptop eventually. It started out with 64mg, I added 64 at the shop initially for a total of 128mb. Recently got another 256mg which they told me maxed it out for a total of 320MB. (OWC seems to be selling 512 chip for this machine though.) So ... to make a short story long, why won't the laptop run Jaguar just fine on 320MB RAM? Because it's a G3 compared to the Tower which is a G4? Maybe the kernel panics on the Tower were caused by insufficient RAM to run X in the first place? Hmmmm. It's running beautifully now, no problems except in my head. Tower was running some flavor of X.1.
