    Took delivery of the new monitor yesterday. It does work with the
15KHz signal, BUT!

    The displays from BASIC (24 lines, WIDTH 80) and NitrOS9 (24
lines) are a bit low on the screen. EOU (25 lines) is so low on the
screen that half of the last line is OFF THE SCREEN.

    Is EOU mucking with something else?? Vertical for BASIC and NitrOS9
start and end at the same place on the screen, but, EOU starts 2 lines
higher and the bottom half of line 25 is off screen.

    The vertical position setting on the monitor only moves the display
a few pixels.
