>When was the last time you bought a blank book?

They do sell them... =)
http://www.tlsbooks.com/blankbook.htm
And I have one, although it isn't blank anymore...

That's my point...  The fact that some people DON'T
also does not make it an imperative for the rest of
the universe.  So in other words, sometimes you are
technically just buying paper and ink, and sometimes
you're paying extra for the way the ink is arranged.

I do believe I've just found most of the information
I was seeking.  Oki Semiconductors' website has most
of the information published in their datasheets as
well as a general j1850 network overview.

Yeah, SAE is the organization who is charging so much money
if you want the specifications from them.  It's their book.
I checked the USPTO, but did not find much.

www.okisemi.com/us has some good info related to their msm6636 product.
I may look into that ford obd-ii manual that was mentioned previously
as well.
