Hey there, I have an all-in-one PowerMac 5500 with a 250MHz 603e processor running OS 8.6. Its slow since she has only 32 MB RAM so I was going to put in two 64MB sticks. Thing is, I can't for the life of me figure out how to to get access to the mobo to install the RAM. I managed to take off the back of the case, but I can't seem to pull anythign out. I see the hard drive, but that's about it. I don't even see the mobo from that view, I don't think. Anyone know how to install RAM or have a guide or anything? My goal is to upgrade the HD to 6GB from my beige G3 (and put a 20GB in there) and from there I want to put OS 9, then 9.1 with OS Helper, and from there install 10.0 or 10.2 using XPostFacto.
