If I pull the drive will it lose all it's data?
No, I have not tried to boot up in Tiger mode....how would I do that?
OK, that model was notorious for video problems. Your data is safe, but you will need a power supply, nothing will feed across the Firewire bus. You are almost out of the woods!
No, just the power adapter, the regular old 45 watt unit, they were used on several models, hopefully you can borrow one. Incidentally, the monitor is actually fine, but the graphics processor that is soldered to the mother board is dead.
