These were for making bulk release prints on super 8. The print stock, which would be slit after printing, would need one row of s8 perforations per super 8 print. Stocks that only had perforations on the edge (1-0) were for making the internegs which the multi-row stock was printed from. There were optical reduction printers that could take one 35mm original and print 4 x super 8 images. So the 1-0 stock would be used in those optical reducing printers to make a master interneg from which the release prints on multi row stock were printed.
Now days the only multi row stock with s8 perforations that Kodak do is the 16mm 3383 print stock with perf at 1 and 3 (unlike double super 8 stock, which has perfs at 1 and 4 - the outside edges that you are referring to as 1-0)
