I would assume it makes no sense to have it in the cable. It is acoustic not electronic. Typically it would be a loop. Data and possibly clock goes in one end.
As a practical example, consider the Packard-Bell 250 computer. No, not the Packard-Bell PC of the Israeli tank driver and his buddies, but the real Packard Bell, maker of consumer radio and TV gear and aerospace electronics.
Since the thing could run from an ordinary wall outlet (something around 1200W) and used only about 300 transistors (and lots of diodes), it's pretty amazing for a 1961 22-bit minicomputer.
It used magnetostrictive delay line memory, which is what I'd have thought that the 2260 would have used. Oh well, I guess IBM did things their way...
