i need to upgrade my 12" PB.
My PB spec: 867 MHz PowerPC G4, 384 MB DDR SDRAM. Currently i have 60 GB of harddisk (but not sure wad type-ATA? SATA? Wad speed?

The question: What harddisk is compatible with my PB? (ATA? SATA?)
What's the recommended speed ? 5400 rpm?
What's the advisable size? (80GB? 120GB?)
Any advisable brand that compatible?
Is 384 MB is the max memory for my PB?

Any other advice for upgrade of this old machine? i still love it though i already bought a Macbook Intel Duo Core.And i want to revive it back.

Thanx in advance.

I'm not sure about the HD, but I have a PB 12" 867 mhz (in fact I'm typing with it) and I have 640 MD SDRAM, so you can upgrade that. (I believe up to 1 GB)
