OK apparently link didn't work... here's the pic:

See row of red LEDs on M8391? On power-up the leftmost LED lights and
goes out. Then the rightmost two LEDs light and stay on...

Richard - it's yours for "the cost of a beer if we ever meet". All I ask is
that if one isn't online anywhere, you make reasonable efforts at some point

well...  the  trick is to have book partially open not   cracked
 
and to have 2  cameras  for fast production copy and uniform  size on the   
size as  cameras  are  fixed
 
clear material flattens  pages
 
sure if  just a  page or  so   a   camera  even hand  held  works...
but if  you are humping pages all day long.  you  need   this  thing!

It's mostly plywood, framing, and some pipe work.

You can take a shortcut and use some old enlargers or photographic copy 
stands for the camera brackets, and posts for them to slide on.
For one quick and dirty one, we used plumbing pipe and a pair of 
clamp-pods.   (common photographic clamps with 1/4"x20tpi mounting thread)
A "slide-rail" positioner is helpful to be able to make minor front-back 
adjustments of camera position, particularly since a relatively long focal 
length lens is going to require increasing the camera to work distance.
For this use, you'll want them coming down from a 
superstructure ABOVE, rather than rising from the base.


The big part is a trough made of two pieces of plywood resting on a V 
shaped frame.  (You'll remember that I recommended NOT having them meet at 
the bottom.)  Draw some lines on it at the midpoint, and at "calibrated" 
distances out from the midpoint, plus some holes at most common positions 
for bench-dogs or fence attachment.


There will still be occasional times when you will want to press glass on 
the work to flatten it.


Most people consider most "modern" lenses to produce reults that they can 
tolerate.  You may need to use a shorter focal length than you might be 
comfortable with.



With a "standard" camera mount, it is easy to switch cameras around until 
you find what you like.



Throw together a quick and dirty one, and decide for yourself what changes 
you need.

Instead  of the two sides MEETING in a V, there should be an open area 
right at the  spine to accomodate the greater thickness of the spine 
itself.   Having the two side panels able to slide up and down, with pegs, 
a few  inches would accomodate that and permit a varying amount of spine  
clearance.

Lighting.  Ideally, lighting for copy work should  be at a 45 degree 
(1/4PI) angle.  That way specular reflection  (glare) from glass cover 
(still needed occasionally!) or even just glossy  paper, is not going 
towards the camera.  If the trough faces  north/south, then that can be 
done with light(s) north and south of the  unit.  Using two lights makes it 
much easier to get acceptably even  illumination. Some people prefer 
various forms of diffuse light, or  coaxial lighting ("ring" light).

Having the camera at a fixed position  relative to the work holder is great 
IFF you are doing consistent  size.  Different sizes could be dealt with 
through variable focal  length ("zoom") lenses, but that is not always the 
ideal solution.  I  like to use FLAT-FIELD lenses, which are generally 
fixed focal length  (sometimes called "primary lenses").  Enlarger lenses 
are an  extremely cheap source for those.  Being able to move the 
camera/work  distance closer/farther requires a movable mount to change 
distance, but  keep the camera centered relative to the work.  North/south 
motion  can be easily handled by moving the book along the trough, 
preferably with  a fence, or simple bench-dog stops.  The other motion 
generally  requires the camera mount to be a pole at a 45 degree (1/4PI 
radians)  angle relative to the work.  Since the work is at a 45 degree 
angle  from vertical, that means that the pole can be VERTICAL, with the 
camera  mount aimed at a 45 degree angle. The post should be offset 
slightly from  the north/south center, with the movable camera mounts 
holding the cameras  at 45 degree angle (preferably with the focal node 
close to that central  plane).

Positioning of the book would require placing it so that it is  centered 
north/south (calibration marks, as well as fence or bench-dogs,  are very 
helpful!) and moving the camera up and down and focussing for  distance.


NOTE: use of other than 90 degree (1/2 PI radians) for  the book holder 
would require further changes!

It should - according to a chart in the 1979 pdp11 processor handbook the 
LSI-11 was used in the 11/03 and the 11/03L.
