On one of my "free darkroom stuff" pick-ups, I picked up an Optographic Lab Color Process Computer. I'm wondering if anybody has an information on this machine as I cannot find anything. I have just started doing RA-4 in my home darkroom and this thing might be fun to play with, if I knew how it worked. There are no probes or anything, it simply has a slot to insert a negative and several knobs. I'll post some pictures later if they will help. Perhaps there is a similar device out there that is more common that I can read up on? I'm definitely NOT expecting this to remove the burdon of learning how to use my color head and adjusting the filtration. Thanks for any help you all can give.
