Well, I was able to get the data off my HD, onto a removable drive: Good However, I am having some serious issues. I was able to wipe+install Tiger, but the cursor kept freezing every so often. When this happened, the keyboard wouldn't respond (ie, command-tab) either. I had to force a shutdown with the power button. I re-seated the keyboard cable, no luck. Now, it won't even turn on. I took the RAM out, left my Apple RAM in. No luck. Could it be my backup battery? http://www.pbparts.com/shop/gbb.html I was not getting "Time/Date set before..." I hit the power button, the HD spins up, but no computer (no chime, nothing). Any ideas? I can try booting from the Tiger DVD again. I could also re-seat my HD cable. Thanks! John
