I'm in the process of developining negs from the early 70's. Mine were not stored properly either. Have done 6 rolls of Tri X at 15 min in straight D-76 with a 3 min pre soak. So far they look pretty good. I also used the anti-fogging agent from Kodak. I just snipped a little for a few tests. Started at 9 min. Next is a roll of Pan X and then 4 Plus X. Try it you might be surprised. I was. Good luck!!(posted 9262 days ago)Richard
