Cleaning out my garage!  Vintage programming manuals. These books may not in pristine condition.  Some of the covers maybe stained and the edges of the books are a little dirty. The pages have yellowed a bit, and some of the books may have succumbed to a little bit of moisture.  However I have made sure that all of the pages are not stuck to each other and the pages are not torn. All of the pages in all of the books are very readable.
