I'm using a number of these in cross-over situations, but it didn't happen first time... Some do, some don't (infact the ones I'm using at the moment do - but only if I leave them in the machines, if I swap the cards over within the same group of machines - they don't (and even then they only "don't" one-way... - If you get what I mean). Summary: Your mileage may vary... I had a lot of cards and cables to swap around with, and I was lucky to find some that work... ;-) (and a lot that didn't)... David Greenman at the time got involved a bit - but between us we couldn't come up with anything definitive... Cables? Cards? Timing? - Timing and Cables? Who knows... (The only interesting thing I did find is that a sequence of 'FFFF-FFFF's repeated would screw the card up one-way only for one of the configurations I cooked together...
