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).
