  1. It should be noted that these guides are written based on a late-model eMac (2005, 1.42GHz, DDR). They will differ slightly from the older model eMacs that use PC-133 RAM. Lay the eMac screen-down on a flat surface. I've found it convenient to use a carpeted floor because the computer is so heavy. Remove the single phillips #2 screw on the RAM door, and remove the door
