But the real reason grocery chains used it was to limit their peak "demand"
usage by cycling coolers (a big deal at grocery stores) and not allowing too
many of them to draw current at the same time.  This was used by more than just
grocery stores (my borther configured one at a VA hospital), but grocery stores
were a big market for the S/1 as I recall.

Prior to the IBM 5150 (original PC), we even had IBM recommend a S/1 as the
interface between an ASCII weigh scale and a S/34.   Seemed like an awful
expensive protocol converter to me!  (And the customer thought so too...)
