Hello! This type of iMac does indeed have one full length memory slot, but it also has a small SO-DIMM slot (which is more commonly used in laptops). Both modules are swappable, but finding a 512MB SO-DIMM SDRAM stick can be tricky (and possibly costly). I think the practical memory ceiling of the iMac G4 is 768MB. Unless, of course, money isn't the issue.
One gigabyte of memory is the maximum you can get in an iMac G4, by the way.
