Over the last months I scanned micro fiches with XXDP diagnostic program
listings.
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:

(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!)
