 ### Half-pixel shift
 
 Fourth, we mentioned above that when we entered in $80 that the Apple didn't display any pixels for this byte.  This is because the Apple uses the high-bit as a flag to shift that group of 7 pixels over HALF a pixel. (Yes, half a pixel.) This means the monochrome *effective* resolution is a pseudo 560x192. We can't individually access every 560 pixels, only part of them so it is not a "true" 560 resolution. :-( What this means in practice is that we can use this half-pixel shift / byte to get very smooth slopes for Y, etc. :-)

 **Note**: The emulators `Virtual ][` and `Apple2js` are *broken* emulators. They do **not** emulate the half-pixel shift of real hardware at all.  This is another reason we won't worry about it for now.
 
- We're going to ignore the half-pixel shift since it is easy to touch up the font data later if we wish:

+At the beginning we said to view the HGR screen in monochrome; Notice how the extra colors make the Hi-Res text much harder to read. If you are running on real hardware the Apple Color Composite Monitor had a push-button on the front to toggle the screen between color and monochrome.  Now we know why!
