    Usable raster is 800 x 275 pixels (80 x 25 characters).  24 lines are
    available to the user and 25th (topmost) line is the status line.
    Status line, if enabled, displays current serial port speed, 16 setup
    bits, and clock.  There is no NVRAM, so setup bits are always 0 after
    reset and clock starts counting at 0 XXX.

    No character attributes are available, but in 'display controls' mode
    control characters stored in memory are shown as blinking chars.

    Character cell is 10 x 11; character generator provides 7 x 8 of that.
    3 extra horizontal pixels are always blank.  Blinking cursor may be
    displayed on 3 extra scan lines.

    On each scan line, video board draws 80 characters from any location
    in video memory; this is used by firmware to provide instant scroll
    and cursor, which is a character with code 0x7F stored in off-screen
    memory.

    Video board output is controlled by
    - control flag 0 "disable video": 0 == disable
    - control flag 1 "cursor": 0 == if this scan line is one of extra 3,
      enable video every 5 frames.
    - control flag 3 "status line": 0 == current scan line is part of status line
    - keyboard mode 'RED' ('display controls'): if character code is
      less than 0x20 and RED is set, enable video every 5 frames; if RED is
      unset, disable video.
