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 apple, system and/or clocks:
“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)
“For the universe has three children, born at one time, which reappear, under different names, in every system of thought, whether they be called cause, operation, and effect; or, more poetically, Jove, Pluto, Neptune; or, theologically, the Father, the Spirit, and the Son; but which we will call here, the Knower, the Doer, and the Sayer. These stand respectively for the love of truth, for the love of good, and for the love of beauty.”
—Ralph Waldo Emerson (1803–1882)
“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)
