Apple II System Clocks

Apple II system clocks, also known as real-time clocks, were commodities in the early days of computing. A clock/calendar did not become standard in the Apple II line of computers until 1987 with the introduction of the Apple IIGS. Although many productivity programs as well as the ProDOS operating system implemented time/date functions, users would have to manually enter this information every time they turned the computer on. Power users often had their Apple II's peripheral slots completely filled with expansion cards, so third party vendors came up with some unique solutions in order to mitigate this problem with products like the Serial Pro and No-Slot Clock.

Famous quotes containing the words clocks, system and/or apple:

    What a devil hast thou to do with the time of the day? Unless hours were cups of sack, and minutes capons, and clocks the
    tongues of bawds, and dials the signs of leaping-houses, and the blessed sun himself a fair hot wench in flame-colored
    taffeta, I see no reason why thou shouldst be so superfluous
    to demand the time of the day.
    William Shakespeare (1564–1616)

    Short of a wholesale reform of college athletics—a complete breakdown of the whole system that is now focused on money and power—the women’s programs are just as doomed as the men’s are to move further and further away from the academic mission of their colleges.... We have to decide if that’s the kind of success for women’s sports that we want.
    Christine H. B. Grant, U.S. university athletic director. As quoted in the Chronicle of Higher Education, p. A42 (May 12, 1993)

    My apple trees will never get across
    And eat the cones under his pines, I tell him.
    He only says, “Good fences make good neighbors.”
    Robert Frost (1874–1963)
