I used to be a devoted Kodak Microdol-X user myself. I have mixed up a gallon of the Freestyle Legacy Microdol-X, but have not yet had the opportunity to test it (yet). I also mixed up Kodak's replacement for the Microdol-X replenisher, which I found on the internet.

I have about about 600' of Fuji Presto 1600, and Microdol-X is recommended by Fuji in their instruction sheet. So hopefully this will be a good combo. I normally rate my Prest 1600 at about EI 640.
