I cant sell you one, but until you manage to find a copy to buy I can point you in the direction of pdf copies of the manuals. While nothing beats a printed copy of a text book I find a pdf file running on a 2nd nearby monitor is pretty good oo 
Just let me know
Hi,
I have a printed version of SAS/C V6 manual.
Be quick : tagged for junk disposal soon.

PS: also, i have an early preprint version of some RKRM manual which was sent to registered C= developpers in pre 90 era., mostly collector item imo. Also tagged for junk disposal.
