I had this same problem when I built a Palomax HD interface for my 500 motherboard. Since it is just a motherboard really, I built it with a right-angle connector so that the interface would like parallel to the motherboard. This did not work. It would work, but whenever the machine would get cranking, it'd get flaky. During heavy IO, I could tap a key on the keyboard (any key, even a shift key) and have a good 25% chance of that action locking the hdgeneric8i.device up. Wasn't pretty. This makes me wonder how the CMI boards, the Supra internals RAM boards, and the PP&S internal RAM boards handle this.
