The big problem with newer faster speed memory in older machines seems to be the density of the RAM. I have tried some PC133 in my B&Ws and some doesn't work at all, some shows up as half of what it should be, and some works just fine.

Quicksilvers looks nice, but I think I like the less glitzy DA's more. Someday I will have the last OS 9.1 native booting G4 made (when they are freecycle finds probably).

2GB of RAM is decent even today, its nice to be able to stuff that much into older systems.
