Compute magazine

Hi, for quite some time I have some magazines of COMPUTE ("Club Of Microprocessor Programmers, Users and Technical Experts"), a gazette sponsored by National Semiconductor, lying around which I consider worthwhile to be conserved for the past. The date I am talking about is around 1975..1977. Some questions: 1. I have only some issues, namely V2N7...V2N12, V3N4...V3N7. Does anyone have other issues (and is willing to scan or copy those)? I'd be very interested in this epoch. 2. Scanning: You find a sample issue at http://www.ais.fraunhofer.de/~veit/v2n7.pdf (2MB). This was scanned B&W 400dpi, stored as TIF and converted with Acrobat. My problem is that even with this some listing pages are barely readable, see page 3 for example. This is probably because of lack of contrast; the magazine is printed on light brown paper with dark brown text. If one scans in color with 600dpi (as in sample http://www.ais.fraunhofer.de/~veit/3x.pdf, 2MB) this will result in much larger files - the raw TIF is 95MB on my disk, which is not a diskspace issue for me, but for downloaders; expect a single issue to be 40MB and more in size. Do the "professional scanners" here, like Al, have a recommendation for resolving this? Regards Holger
