I just got a tangerine clamshell iBook w/ 64MB (1 slot free), 6GB hdd, OS9, MS Word 98, all install CDs, and matching USB floppy and Epson printer and extra battery all for $125. I doesn't have the Airport card, but everything seems to be in great shape. 1. Where is a good place to learn about these early iBooks and OS9? My only experience with Macs has been with OS X. 2. When I bought it I was told that the battery did not hold a charge (no surprise there!) and that she had an extra battery that came with it that she could never find how to use. 2a. When I power up using the ac adapter and the installed battery, the charge ring is orange (normal), the battery indicator in the top right looks about 4/5 full with a red arrow at the bottom, and the battery indicator in the bottom tray shows a battery with a plug across it but with all bars clear. Can I assume that means that for some reason the battery is not charging? 2b. When I power up using the ac adapter and the installed battery, the charge ring is orange (normal), the battery indicator in the top right shows a battery with a lightning bolt though it, and the battery indicator in the bottom tray shows a battery with a lightning bolt though it but with all bars clear. After a while the top indicator changes to a battery with an X over it, and the indicator on the bottom shows a plug only (no battery). Can I assume that means that the laptop tried to charge it and could not for some reason? 3. What is the best way to clean the plastic on the machine? Is window cleaner and a soft cloth OK? EDIT: Also, what about expansion? Is there any advantage to expanding the memory beyond 64K for OS9? I understand that you can run OS X on these with enough memory, but I only want it for occaasional internet usage on the road, so I don't see any real point to that (but it might be interesting just to see it).
