I would assume it makes no sense to have it in the

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...
