[G4] Startup chime but no dice!

[Jay E. Krauss Jr]

Jeff,
	The MDD is designed to start up in Firewire Target mode. 
Since your G5 has Firewire, you could attempt to boot the MDD with 
"T" depressed (presuming some message gets from the keyboard to the 
MDD's "innards"). I'm not sure how much of the MDD's logic board, 
RAM. etc is required to get into Firewire Target mode, but even if 
there is no video from the MDD, the G5 (if Target mode entered) would 
see the MDD's first (only?) hard drive. You could then inspect the 
drive to see what was on it and (possibly) run repairs with Disk 
Utility, DiskWarrior, TechTool, Drive Genius, etc. This, of course, 
does not permit checking the logic board or RAM of the MDD, and even 
if hard drive access and repairs were possible, the MDD may still not 
boot if there is a logic board or RAM problem.
	Just a thought.
Jay
