The graphical interface was the Windows menu bar and pull down items such as load, save, etc..... So that is self explanatory I hope.
The model allowed the emulsion engineer to have a CAD / CAM type program at his disposal to figure out mole % of halides and other addenda, to predict crystal habit and to warn about scaling problems. That is what Kodak gained.
In addition, the program linked to the database of chemical addenda so that an emulsion maker could select ingredients that were optimum for his / her emulsion.
It made emulsion engineering quicker, better and less expensive!
All products since about 1988 used some form of the model.
There, I hope I answered all of the questions Ray.
