I have CDC drive cables EXACTLY like those, they are ribbon cables,
about 24 ft give or take and they are twisted paired ribbon cables...
'Twist-n-flat' ribbon cable was very common, and was still in the
catalogues last time I looked. That's ribbonm cable with twisted pairs
that ahve untwisted bits (a couple of inches long excH) every so often so
you can crimp IDC conenctors to the cable. Of course all 'flat' parts
have the untwisted wires in the same order. That stuff was very common
for disk drive cables, etc.
I would guess tour CDC cables are for SMD drives, which used differential
ECL signals IIRC. Tiwsted pairs are of course ideal for such signals.
