Compute magazine (retry)

[Holger Veit]

Somewhere my last posting didn't find its way to the list, although 
there were some downloads of the files below.
Retry (with few typo corrections)::

Hi,
for quite some time I have some magazines of COMPUTE ("Club Of 
Microprocessor Programmers, Users and Technical Experts"), a newsletter  
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 5 for 
example. This is probably because  of lack of contrast; the magazine is 
printed on light brown paper with dark brown text; other issues use blue 
or green text color which is probably even less readable in a scan. 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
