I'm not aware of any film called "Fuji Neopan Archos." I suspect you mean Fuji Neopan Acros. (Note, too, it's "Acros," not "Across," which is a common mis-spelling of this product's name.) I'm not trying to be a jerk in pointing this out; it's just that if you did a Web search on "Fuji Neopan Archos," chances are you'd get few hits because of the mis-spelling. In fact, I just tried, and the incorrect spelling yielded 371 hits, compared to 65,800 for the correct spelling. I didn't bother looking for development times on either search; as Patrick points out, it is listed at the Massive Dev Chart. I can't comment on the accuracy of those times, though; I've never used either Fuji Acros or Ilfosol S.
