Welcome to the Intel® Embedded Community.
I see that it's been a couple days since your post and no "old geezers" have come to your rescue. This might be overly simple, but have you tried to google the title of that manual? I know there's a bunch of websites out there that store old archvied manuals, specs, datasheets, etc. Some are free and others charge a nominal fee. Below are a few examples. Maybe these are docs you already have but I thought it might be worth taking a shot if you haven't already.
I hope this helps.
