Extra credit if you can read that hires text on an Apple ][ color monitor (or NTSC color TV), where you get one color per two pixels, with seven pixels per byte, and some very quirky rules for figuring out the color!

The Apple II's Hi-Res mode was peculiar even by the standards of the day...

Each pair of adjacent pixels generated a single color pixel via artifact color, resulting in an effective resolution of 140×200. The lower seven bits of each byte represented the pixels, while the most significant bit controlled the phase offset for that block of pixels, altering the color that was displayed...

Finally, another quirk of Wozniak's design is that while any pixel could be black or white, only pixels with odd X-coordinates could be green or orange. Likewise, only even-numbered pixels could be violet or blue.[4] This is where the so-called "fringe benefit" comes in. The Apple video hardware interprets a sequence of three or more turned-on horizontal pixels as solid white, while a sequence of alternating pixels would display as color. Similarly, a sequence of three or more turned-off horizontal pixels would display as black.
