I have a question....I have and love my g3 but it only has 128 mb of memory and I would like to get e memory upgrade so I canI need to get a new install some of the newest software. The guy at the computer store told me I really need a new computer, mine works just fine and I only use it for fun. I think he was tring to get business because he is the closest mac reseller or service plan in 600 miles ( Ilive in the middle of nowhere). He told me he could upgrade it for $450 to 512mb. I think he is trying to take advantage of me. To make a long story short (I didn't really so that did I). Is there anyway I could purchase a memory upgrade online somewhere and install it myself? I'm not to technical, but I am also not a complete idiot.
