When my 1302 moved from my old IIcx with video card to the ne ci with internal video, it needed a new cable. The sense lines basically involve a special ground configuration. One other thing you need to be careful about is the physical construction of the cable head. On the vidoeo card, the port is out in mid-air with nothing around it. With the ci/si the port is surrounded by the case. and their is very little clearance around it. THe up shot is that when I got the pinouts I made my own cable, but it wouldn't fit because the shell of the head wrapped around a bit to far (to hold the shell together) and butted against the IIci case. THe solution was to buy a premade cable (I got one from Software that Fits) with a molded (rather than assembled) head. This fit great.
