Another thing that was so vast with IBM S/370 "old iron" were the
monster data cables, given that a SATA cable is about the size of a flat
shoelace.

My very first task at IBM (late 1975) was helping to dismantle the Data
Centre near Cavendish Square. The drives would have been 3330's and each
string needed two unwieldy cables about one-and-a half inches thick
("bus" and "tag" ISTR) with huge connectors guaranteed to snag on the
false-floor supports when you pulled them out.
