Does iBook G3 RAM work in G4 iBook?

[katkramer]

I have two iBooks...a G3 and a G4. I've put the G4 up on Craigslist in Austin, and was typing up the specs when I found out something absolutely amazing...the G4 only has 768MB of RAM!!

I'm a graphic designer type, and I've been using this silly iBook for several years, running PhotoShop, InDesign, Dreamweaver, GoLive...and NEVER KNEW that it didn't have very much RAM. (Take that, Vista!!)

I originally upgraded the G3, and I'm wondering if I can put the G3 iBook RAM in the G4 iBook?

Any info appreciated...
