512MB PC133 SODIMM Memory RAM 144pin sdram

These were taken from Powerbooks.

They will work in all Powerbook G4 Titaniums and Aluminums (except the Powerbook G4 A1138).

Apparently they will work with certain iMacs and iBooks, but please do your research if you buying these for those.

These come in various makes, a couple are pictures.

I'll do what I can to make a matching pair if you buy two.
