I'm keeping it as a classic machine, got the iBook G3 for Mobile Tiger. I pulled one of the 64MB chips and stuck in a 128, 196 MB should be fine for 9.1.
My battery is the same as yours olePigeon, about 3 mins of charge, it may actually be possible to open the battery and put in some new cells, I need to look into this.
I got extra lucky in that there was an Airport card already installed too
I've also got an IDE to CF adapter en route at the moment, I was going to stick it in my Beige G3 but I'm thinking it would be great in the Pismo, 8GB CF vs ancient 6GB IBM drive.
BTW, does anyone know where I can download 9.2.1/9.2.2 updates? Apples site keeps giving me a not found error.
