Photo Techniques evaluated the new emulsions with several developers and suggested that you first try them with NO CHANGE to your development times.
They did development tests to try to match the same contrast index as with the old films to come to this conculsion.
It's the old stuff
Thanks to all who tried to help. I was able to make a positive ID on the film.

This provided a Zone VIII density of 1.25 above FB plus fog.
This will not be enough density for anything other then enlarging, however. Even Azo Grade three will accomodate a density range (high density minus low density) of 1.35. That would equate to a Zone VIII density of 1.45-1.50 above film base plus fog using the typical Zone System method of expression.
