My uncle recently gave me a 1999 Powerbook G3 333 Mhz. I think he said it had 700 mbs of memory but I'm not sure of that. I have a few questions about it: Can you upgrade a powerbook G3 from a 333 mhz to anything faster? If so where can you get a processor that will fit? Also how much RAM can you add to it total? And lastly can you add a fire wire port to it? It currently only has usb's. I am a little rusty on Macs because I haven't had one for 3 or 4 years but I would like to get back into them. I would really appreciate any help. Thanks in advance for the help.
