@bkmoore773, thanks! I have a G-Tech 500 GB, but it is a Q-Drive (four different connection interfaces) vs. the two interfaces (I think) on the earlier drives. Either way, it is a great, solid and fast drive.
I managed to create a network bootable disk image on my 17-inch iMac. I then used that image to simultaneously boot both my 2006 Intel iMacs as diskless network clients off of a PowerPC G5.
That's what this group is for. To show each other our cool Macintosh projects and give each other ideas. Steve Jobs demonstrated network booting in 1999. He was quite the showman, you can see it here: OS X Server Introduction.
