Hello I picked up a PowerBook G3 (model identifier 312) at an auction for $30. It's running OS 9.2, and is in surprisingly good shape. I plan to upgrade it to OS X 10.2, but the more pressing issue is that the battery is completely dead. It only works with the charger. I priced some online, and they run about $99. Wondering if anyone knows of a better-priced battery source that I may be overlooking. Also, wondering how it will perform with 10.2. Anyone else have a similar setup? Thanks.
