Thanks for the tip, Greg. I did try the Wayback Machine to pull up URLs that hosted the J-107 publication long ago (that I found in Google Groups discussions), but the docs appear to have disappeared before they were crawled. Lots of dead redirects. I’m not sure how to search the Wayback Machine directly although I did try that too without success.
I’ve searched pretty hard for this.
There is some chat about J-107 on Google Groups, for example here:
https://groups.google.com/d/topic/rec.photo.darkroom/2tEoTJZhYYU/discussion
One Dana Myers features frequently. For example here:
https://groups.google.com/d/msg/rec.photo.darkroom/OmXKne2ELBk/UpE8c5sgReMJ
Myers has Instagram and Twitter accounts, but I don’t so can’t contact him via that medium. He seems like the kind of guy who might keep publications like that on an old hard drive.
Other familiar names in those old Xtol discussions include Paul Butzi and Dante Stella. Maybe I need to bug these strangers. I know I have a record of practically every PDF file I ever downloaded. Maybe they do too.
