Hello,
I understand your frustration. After seeing a recent ebay listing, link here:??(I only included this link so you can have a picture of the cover which was useful in my search below)
Well, needless to say I was partially upset that I missed that while on vacation =/. Still, I became revitalized at searching for this again. I ended up finding this link googling "8673C Volume 2 Manual" which the ebay pics helped.
Its diagrams are "broken up" or "cut up" in letter format but at least one can actually read values on this schematic. I haven't had the time to see if its complete or missing something though it seems to have "continuity" when I looked over one component diagram. Hope it helps. Kudos to the guy who took the time to scan it for free.
