I'm stressed about getting a new/used keyboard for my G3 12" ibook. I want to buy used, cause it's just the spacebar that isn't working anymore. I am wondering about a couple of things: 1) Can I use the keyboard from the G3 500mhz ibook ? (mine is the 900mhx version) 2) Some G3s use a keyboard with a green connector ribbon and mine has a grey/clear one -is the green one compatible? 3) Can you fit a G3 14" keyboard into the 12" model. I'm going nuts trying to figure this out, so any help would be appreciated. Thanks!
