HP 5036A microprocessor lab - searching for copy of "Practical Microprocessors"

You're doing something wrong... Probably scanning at too high a resolution, or scanning in colour or high-bit-depth greyscale (which for >80% of computer documentation is completely unnecessary). A few hints: * Scan in black and white, 300dpi. If you absolutely have to have greyscale, turn Descreening on and reduce to 16 shades of grey. Most of the time even greyscale is unnecessary -- most printing technologies don't do true greyscale (read up on dithering and halftoning if you're interested). As long as you scan at an integer multiple of the print resolution (and set up Descreening properly), you'll get a perfectly good scan. * Most mass-printing technologies only go up to 150dpi. Scanning at much beyond 300dpi is a waste of time. * TIFF with LZW or Zip compression usually does a pretty good job of greyscale, and TIFF with CCITT Group 4 FAX encoding works wonders on B&W. Think 40kbytes per page. IrfanView can handle all of these formats and batch-convert from just about any image format *to* just about any image format. If you're using *nix, install ImageMagick and "man mogrify". * If you want a PDF file, grab a copy of Eric Smith's "tumble" program: <http://tumble.brouhaha.com/> -- it converts a directory full of TIFFs into a single PDF. It's a little long in the tooth, but still about the best tool for the job. I've managed to compile it for Windows (using MinGW) - if there's any interest, I'll see if I can dig out the executable. I'm willing to host the resulting scan (although I suspect Al Kossow / Bitsavers might be interested as well) but not if it's a 1.2GB file... I'd be happy to take a look at one or two scanned pages and try and offer some assistance though. -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
