I just recently obtained a powerbook G3 for free! The only downside, I have to wipe it clean and reinstall the OS (10.3) and it did not come with an installation disk. My local Apple store does not stock these. The box has firewire which is a plus. It only has 186mb memory when I go into the OS. How much memory can I upgrade to? Does regular 100mhz memory that goes in PC laptops work in the G3 as well? Sorry for all the questions. I am really new to the PowerPC architecture. I only have worked on Leopard intel based mac's. Also, the battery wont charge. I have tried the reset on the back by the RJ11 and the video card and the battery light just flashes green when I hit the indicator. It has been plugged in for about 3 hours and still shows 0%. Thanks!
