[ARC5] [MRCA] AN/PRC-74 Schematics

I'd say skip the oversize scanner option because it can become expensive.

 When I was into audio visual library work many years ago - I used a copy
stand - sort of a pole on a base  with a vertically adjustable platform to
mount a camera.  Most digital SLR's are of fairly high pixel count that
they will meet or beat the resolution of most consumer scanners. I bought
my copy stand at Boeing Surplus in Kent, WA. years ago for 20 dollars. you
probably can ask at a local camera shop or Craig's List. Also,  most heavy
duty tripods have head/column that can be reversed for a makeshift copy
stand.

Even a decent point and shoot will work in a pinch-  I had a mother-in-law
that was a genealogist and needed a portable copy solution - I made her a
 set of  T bars of 1" x1/2 oak about 30 inches long  that had a series of
 spaced holes drilled in the vertical sections they were assembled together
form a self standing "X" with a 1/4 x 20 bolt in the center that held a
point and shoot or a lightweight SLR . It was a plan I  had obtained from
Petersen's Photographic in the 80's (I can find it,  if someone is
interested)  It is ideal for locations where you can't take the the
document out of the library/museum/archives  (always ask FIRST - many
locations forbid photography - some don't).

You use 2 copy lights at a 45 degree angle on both sides of the camera.  If
copying a document that wont stay flat use a clean sheet of glass to hold
it down.  you can use a circular polarizing filter if glare is a problem.

There is a very dedicated group of amateur book lovers out there that is
trying to scan older copyright expired books -  they have a specialized
stand that allows 2 pages at time  to be scanned and and have software to
correct and organize the pages - most of them donate their work to
Project Gutenberg. if you are interested in saving your valued copyright-
expired books and sharing with the rest of the world you might want to look
into this option at:

I must say - even though it is somewhat off topic - I have a deep respect
for those individuals that have dedicated themselves to making
the technical books/manuals  available online - there are many, but two
sites I use often are:

http://bama.edebris.com/manuals/   BAMA Archaives

http://www.tubebooks.org/technical_books_online.htm   Pete Millett's
Technical Books site

If you have a scanned book or document that is of expired copyright- please
consider donating to these sites so we can keep the "knowledge of the
ancients" alive.
