DEC PDP-11: 330 XXDP listings scanned from micro fiches

Hi all, Over the last months I scanned micro fiches with XXDP diagnostic program listings. These listings are essential for repairing PDP-11's (or enhancing SimH). I digitized 330 listings from 452 fiches, with a total of 53545 document pages. Almost all of them should be new stuff. The PDFs are ready for download now. Until they appear at bitsavers.org, you can use my link: ftp://u58104846-pub:open4you at ftp.j-hoppe.de (Note the embedded user/password strings) The scans come in two versions: "high quality" and "black&white": The HQ version is gray level and contains a true image of the micro fiches, after non-destructive contrast enhancement. It is the base for further image processing. Download path is ./fichescanner/hq/gh The BW version is compressed to black & white and aggressively optimized for size and letter quality. File sizes are 20x smaller than the HQ version. Its intended for daily use and OCR, but for some very problematic fiches textual information is lost. Download path is ./fichescanner/bw/gh And there is a background article on http://retrocmp.com/projects/scanning-micro-fiches describing the self-build automatic micro fiche scanner (video!) Enjoy!
