Just a small update:
I returned home after work on Friday, and I swapped the 20GB IBM drive with my 40GB Hitachi drive from my long-deceased iBook G4. Despite this change, the Powerbook (now Halfbook, since the LCD, and keyboard have been removed for the time being) still refuses to boot directly from the HD. I end up getting this:


As a result, I tried booting from one of the OS 9 discs, and the Halfbook managed to get to the main desktop.
To my surprise, the HD icon also appeared on the desktop, and I was able to browse the files that were on it for about 30 seconds, or so before the system would hang (I haven't quite figured out why it is doing this).
I'm now thinking that either the logic board, or that stupid yo-yo adapter is at fault.
Thoughts?
