You might try a company that reconditions/upgrades existing equipment.
They typically will have inventories of old bits and pieces.

One that comes to mind is Neutronix/Quintel, Although I haven't dealt with
them lately, they've always been responsive to my needs and produced
quality work.

Let us know how it works out.

This question is posed to any litho people that have experience with state of
the art equipment circa 1970.

Does
 anyone know of a company that still makes a "photoresist camera"
system, where I could just purchase that projection subsystem of a
photorepeater? I am ideally looking for 1:1 projection, with a field of
view, conveniently, of about a 1" square or a 35mm circle would work
too. Projection requirements would be reasonable. Seems like something
out there has existed in the past, but trying to go through old Nikon
Ultra Micro Nikkor catalogs doesn't mean I'll be able to find anything
out there today. I feel like this isn't too complicated of a
requirement, but I can't seem to find anything without going out and
spending quite a bit of money to have someone do a projection system
from the ground up.

Any thoughts?

Thanks,
David Casale
