Hi, I have 80 pin SCSI discs mounted in hot-swappable trays on a SCSI backplane which takes care also of powering them up and of SCSI termination. This is one way of using them. I also have the same drives in a different system connected to normal SCSI LVD cable using small adaptors which have an 80 pin receptacle on one side and a 68 pin SCSI connector plus 4 pin molex power connector on the other, as well as jumpers to define SCSI id. In this second case you have to provide the required termination of the SCSI bus (e.g. using the right terminated SCSI cable). alfredo
