I couldn't get your mailing address to work ... so I am posting this to
the network.  We are seriously considering acquiring an Eikonix 1412 ...
this is a 4096 x 4096 pixel x 12 bit CCD linear array stepping camera ...
we would want to connect it to a SUN-III/160C-P8 system ... we were given
a quote for a SUN3/VME-bus interface including "... hardware, 12' cable, 
documentation, and Driver / Library software package with full support."
I had expected this system would work immediately on installation w/out
the kind of tinkering you mention in your note.  I would appreciate a
summary of your experience with this camera system and it's support ...
including (if possible) a report on photometric performance, signal to
noise ratio, sensitivity, scan to scan variability, and ease of use by
email to annala%neuro.usc.edu@oberon.usc.edu.

Thanks, AJ Annala, USC Neuroscience Program

p.s. (1)  I am told that Eikonix is a subsidiary of Kodak.
     (2)  There has been some suggestion in this newsgroup that 
          re-Kodak products were somewhat difficult to use
     (3)  I would like to know what kind of light box you use
          with a 12 bit camera that can guarantee photometric
          uniformity and low noise ... and/or how much frame
          averaging or time integration you need to do to get
          a low noise image anywhere near full precision of the
          device.
