Well, I go away for the weekend, then come back to find another project waiting for me!
To answer some of the questions:
I can do it. In fact, I have done it before. It will not be 18 days, however. It will take me a couple months (2-3) to get everything scanned in and processed/PDFed, and the CDs made and tested.
If I did it, what you would end up with is this:
A CD-ROM with all the manuals on PDF, in sections as is appropriate. There'd be an autorun for PCs (though the PDFs would be viewable on any computer (Mac) that can read ISO CD-ROMs and has an Acrobat Reader program available for it. The PDF files wouldn't be searchable, since I'd be scanning it in as a graphic (OCR would take longer, and I don't have the best software for that); however, the PDFs would all have bookmarks as is appropriate. The quality should be very good, and the page zoomable (default on-screen display would be like 70%, so you could magnify the remaining to 100% to see detail).
Also, I'd have to lop the binding off the manuals, but if it is already drilled for three-hole binders, then they'd go right back in.
