Powerbook Memory, iBook Memory Upgrade, MacBook Memory Apple Powerbook G3, G4, Pro My G4 is form late 2005. Which reminds me, I said to MR I thought I'd be able to edit/collate the Hundred and eight verses by the end of 2005, was it? Or was it 2006? I forget now. It charms me that my computer was produced in the same year as we were finishing the 108 verses. I'd like to bring it back to perfect working order!
