At least the first 3 issues of the Mark-8 Newsletter
were published by
 Hal Singer using a ditto machine. I have copies of these issues which
 range in quality from faded and smeared to _really_ faded and smeared. I
 would like to try to "restore" these items to readable form - anybody
 have any ideas? The worst pages are faded beyond simply photocopying
 and/or OCR - I'm wondering if there may be some way to chemically "lift"
 the images, UV light, etc. 
Some of the pages that I scanned were _very_ hard to read by eye, but modern
image editing programs have some great tools in them to deal with that.  I
scanned them at very high resolution and in full color, then used contrast
enhancement, color filters (some the originals were on colored paper) and
de-flecking tools on a number of pages with good results.
You might want to download the trial editions of Adobe Photoshop Elements or
Jasc Paint Shop Pro and try it out.
