Dustpuppy, my Indigo. When I got it, I had to solder in a new tod chip battery to get it to work. Unfortunately the new battery is depleted again in the meantime. So current status is: It powers on, it also gives a display on the monitor, but there it repeats the well know message about tod. So the hinv below has been taken, when she still booted up properly.
