The way Spooling was done on the pre-S/360 systems, to my
recollection, was with a second computer. The 1410 did I/O for the
7010, for instance. The 1401 was used to to card to tape and tape to
printer for larger computers. The first general multiprogramming
capabilities that I recall were in some of the IBM special purpose
systems in the early 60's like the SABRE airline reservations system
or the so called "defense calculator" project that kept track of
radar threats. The operating systems I used in the 50's (SOS, FMS,
IBYSYS) had no multiprogramming. IBSYS for the 7094 may have picked
up this capability near the end of its life in the early 60's, but I
didn't use it by then. Anyone remember?

Does anyone remember where the term spooler comes from? SPOOL =
simultaneous peripheral operations on line. The OS/360 Reader-Writer
was the first multiprogramming capability that was released.
SPOOL was available on the 7000 series and the 1410 long before
OS/360. Multiprogramming was available in the late 1950s or early
1960s, depending on whether you go by announcement dates or ship
dates.
