    You might want to research the meaning of the acronym SPOOL. (Simultaneous Peripheral Operation Off Line) for similar setups.

    Back in college days, I remember executing numerical Fortran programs by running my
    punched cards through the card reader. Then we would wait in the reception area for
    our output sheets to be printed out. During the final weeks of the semester,
    there would be a loooooong line of students waiting for their prints.

    And I vividly remember the Post-Mortem Dump....

    Reviewing some information about ARM series of micros, out of curiosity......
    I wondered whether "super scalar" and "pipelining" was a post-Mainframe
    innovation. As I found out, there had been early implementation of these concepts
    during the 70's in the Mainframe universe.

    Any comment would be appreciated!

    Goes back farther than that--try the IBM 7030 for example--or the CDC 6600. Vector instructions are slowly making their way into MPUs, but mainframes had them as of the late 1960s.

    I wonder whether there would be ever be a documentation about
    people who came up with the idea/design of these concepts...
