You're right Eric, 125 is a typo. It should be 128. I rmember adding exta memory when I bought the G4. And I turned on the virtual memory a while ago to see if that helped. About this computer says, "virtual memory 140 mb used on Mcintosh hd." I've never had much luck downloading, upgrading, etc. basically through lack of knowledge. How would I upgrade to OSX whatever. I guess my initial question was can I add memory? I remember on my old LC475 (which still works like a charm by the way) I upgraded to 7.2.2 (a techie did it for me) and added memory (forget how much) and it was its limit. I assume the G4 has a limit too. I assume G4/350 means the machine's speed. Mine is 400mhz. I'll try adding memory to the applications . . . if I can. thnx, jim _________________________________________________ For information concerning the MUGLO List just click on http://muglo.on.ca/Pages/joinus.html Don't forget to periodically check our web site at: http://muglo.on.ca/
