Yes. But reading the original mail I suspect that the disks will
be mounted in the same rack as the machine / controller. So I think
the cables will be less then 2m in length and you will get away with
ordinary ribbon cable. I know the twisted pair ribbon and shielded
cables, but I prefere the round cables that I got from that old
Sequent S27. I doubt that this cables will have the exact impedance
but they work with my QD33 and the NEC D2363 disks.
