Hello, we all have to thank AXEL for these documents !
I contacted him some days ago about his MC-12A picture on his website :

He searched everywhere in his hard-drives and found two scans of the manuals.
The pictures had black margins with text inside.
With my favorite image processing software (Aperture) i corrected it, sometimes with letters by letters words reconstructions.

Here are the manuals :

Thanks you again Axel !
