The flying leads on my Xilinx Parallel Cable III won't last much longer (they are starting to break at the 9-way housing), and I haven't been able to find a replacement set. Harwin M20 crimp terminals and housings are very similar to the original ones and I have found that with some care, the cheap ratchet crimp tool I got for Molex terminals can be used for crimping the Harwin terminals. My assembly will be more convenient than the original Xilinx one, as I'll put all six terminals into a single 6-way housing.
