Thanks That's a good question - a lot of earlier machines were able to use later RAM which allowed more than what Apple declared as the max. However your machine took just one card with 256MB on the logic board. I'm not aware that 2GB cards were ever available in PC2100 DDR266, unless someone knows better. -- Best wishes Malcolm Cornelius - The Powerbook Fanatic http://www.pbfanatic.co.uk
