Ages ago, on a whim, I bought a second-hand Zero Image 4x5, and more recently a suitable DDS to go with it; My intention had always been to use Direct Positive paper, but just today I saw this thread in the LF forum http://www.apug.org/forums/forum44/1...-film-4x5.html which gave me to wonder about how it might be possible to use FP100C with the Zero?

Is it limited to using a Polaroid back or are there cheap/dirty options?
