I think Fred indicated you need a retina, not the camera.
These retina chips are hard to come by, and their traces are very delicate,
albeit they were revolutionary for their time. I had designed a replacement
chip for the interrim for the R1D (which could have been extended to the
optacon II) on the workbench years ago, but it cost far more for the
technician easily to solder it together in its several layers than it it for
the retina chip prototype itself, and also I didn't see a tie when they
would produced in number through automation to bring down the Many hundreds
of dollars price. Still, it worked in principle, although I did not test it
in everyday rough-&-tumble optacon situations. For instance: it was easy to
get the 6*24 columns done by using several discrete photosensor chips, a
tiny circuit board on which to bind them, the multiplexing/demuxing was
easily programmed into a field programmable logic device, miniaturized by
ORCAD/Pspice, make a test cable of I think it was 14 wires (teflon-covered
for their very small diameter for which one should use special teflon
removing tools lest the stuff just become a stringy mess), I still had and
do have some of the 14 or 16 pin plugs which using a rezin rather than
vulnerable plasstic were easily soldered (whereas the plastic ones for
crimping onto cables tende to melt), and that was that. In addition to
engineering commonsense, there is certainly enough in the optacon's
schematics (which Dave Godfrey in merry ol' England was so Kind and very
helpful to send me years ago) easily to reduplicate the drivers as they then
were for the prototype replacement retina chip. It came town to cost vs the
use of valuable technician tine, my money (which can be analgous to food to
a famished man!),, project time, and the small need for them (yet essential
for those who do need them(
Mary, do you have an R1D, R1C or optacon II with Fred in need of repair?
Perhaps I can send him one retina assembly intact albeit he should inspect
the cable, and possibly resilicone around it and shore of the strain release
since these things are decades old and even silicone dries out eventually,
and leave the craits of stuff until a better day, or until other do it for
me.Charles

Good afternoon.
I sure do miss my optacon. The tech is in the quest for a camera. I bought a
lot of things at Bath & Bodyworks. I need to organize the fragrances in
their respective categories. I don't have a scanner.
Charles, have you and Fred been in contact? I don't want to get a Pearl
Camera, I'll buy one if I have to.
