[NTLK] NewtonTalk Digest, Vol 38, Issue 42

[Matthias Melcher]

Meh. To answer myself: Sharp LM48019K. Sorry, but I can't find any of the docs I had. If you don't have the exact matching document, I'll be happy to connect my scope to a live unit and give you the findings. I'll also dig for the color version.
