 		 #119757 - you found a better link than the one I
Responding to: ???'s previous message
It's probably one of these:

Great, you found a better link than the one I found, it even includes the appnote I have on paper and stated I could not find a link to.

Anyhow the 'best serial appnotes' link is to National semi appnotes, including the 'ten ways to baulletproof 485" and nobody should even attempt 485 without reading that one.
