Short raw clip to follow up on my previous post about the HDSP-2000 hybrid on ceramic LED chip. This is what happens if you tie the output of the shift register to its input after having injected a few bits! I did this as a way to quickly test them. This one is from my good HP 9825. All the ones from my HP 9825 with the over-voltage sure were dead :-/ . But at least we can look inside them :-)
