The OS/360 readers and writers weren't that bad if you used reasonable block sizes, but ASP and HASP make that unnecessary. My HASP experience started with HASP ii V3, although I read much older documentation before that.
I believe that SPOOL dates from around 1959, -- Shmuel (Seymour J.)

My memory is not great these days, but I think I remember installing a "prerelease" in early or mid 1967; and I slightly remember a reference as "Houston Automatic Spool with Priority" — but the "with" in the name might have been during a telephone conversation with someone in Houston. During that early period the documentation was rather rough and (again, if I remember correctly) printed with a TN train. HASP was a wonderful invention! The "OS/360 Readers" and "Writers" it replaced were guaranteed to produce nightmares. (And I do not remember the correct names for the Readers and Writers. It has been a long, long time since I have seen any mention of them.) Spooling was not a new concept, of course. The 7090+1401 and the later DCS systems both quickly illustrated the strong advantages of spooling ---- especially when punched cards were involved!
