- @Blast: I have made an interesting contribution, which is the discovery that in addition to drawing characters to the screen as the electron beam sweeps across the left to right, it's also possible to draw text characters during horizontal retrace (the time interval during which the electron beam is returning to the left edge of the screen to begin the next scanline.)
Because the beam is moving much faster during horizontal retrace, the characters drawn during this interval are faint (less time is spent energizing the phosphor) and stretched to be wider (the beam travels further for each "dot" in the char bitmap.) And of course, the characters are also mirrored, since the beam is moving in the reverse direction.
The 3 shades of green are created by energizing the phosphor only when the beam is moving forward (normal brightness), energizing the phosphor only when the beam is moving backwards (dim) or energizing the phosphor as the beam passes over it from both directions (extra bright). - isokadded on the 2022-10-12 10:29:45
