Apple II Graphics - Peculiarity of Graphics Modes

Peculiarity of Graphics Modes

The graphic modes of the Apple II series were peculiar even by the standards of the late 1970s and early 1980s. One notable peculiarity of these modes is a direct result of Apple founder Steve Wozniak's chip-saving design. Many home computer systems of the time (as well as today's PC-compatible machines) had architecture which assigned consecutive blocks of memory to non-consecutive rows on the screen in graphic modes, i.e., interleaving. Apple's text and graphics modes are based on two different interleave factors of 8:1 and 64:1.

A second peculiarity of Apple II graphics—the so-called "color fringes"—is yet another by-product of Wozniak's design. While these occur in all modes, they play a crucial role in Hi-Resolution or Hi-Res mode (see below).

Famous quotes containing the words peculiarity of, peculiarity and/or modes:

    The peculiarity of sculpture is that it creates a three-dimensional object in space. Painting may strive to give on a two-dimensional plane, the illusion of space, but it is space itself as a perceived quantity that becomes the peculiar concern of the sculptor. We may say that for the painter space is a luxury; for the sculptor it is a necessity.
    Sir Herbert Read (1893–1968)

    The poet ... like the lover ... is a person unable to reconcile what he knows with what he feels. His peculiarity is that he is under a certain compulsion to do so.
    Babette Deutsch (1895–1982)

    my brain
    Worked with a dim and undetermined sense
    Of unknown modes of being; o’er my thoughts
    There hung a darkness, call it solitude
    Or blank desertion.
    William Wordsworth (1770–1850)
