A bit late, just saw the date of the OP and last reply, but maybe this will help someone else in future with the same questions.
The ZD back works with the AFDII (that's what I have). The RAW files work fine with Silkypix.
I think some of the older backs need to be tethered, and may have specific cables and software.
I would also check whether any updates would be needed to firmware, as that might prove diffcult.
Phase One incidentally have a user forum and their technicians will do their best to help solve issues even with old unsupported kit.
