You must mean an AppleColor //e composite monitor, right?

It would be very difficult to use a IIgs monitor with a //e and //c...

The Color Composite monitor is a marvel at extracting enough
luminance bandwidth to produce a readable 80-column display where
conventional composite monitors have a hard time doing more than
40 columns.  But any composite scheme is hard-pressed to deliver
real crispness.

The Apple II video system is limited to 192 vertical lines and 280 (normal)
or 560 (double hi-res) points per horizontal line.  The low horizontal
resolution, however, should not prevent the dots from being sharply
defined.  That is a property of monitor bandwidth and drive.

You should adjust your monitor's brightness so that black areas
are just black, not past black.  Then increase the contrast until
suitable "brightness" of highlights is achieved.  This should produce
optimum dot resolution--so that although you may wish for more
dots, you will have sharp dots.  ;-)

BTW, don't use a long video cable, particularly one designed for
audio.  It may contribute considerable shunt capacitance, which
will reduce the available video bandwidth.

Try putting in hard carriage returns every 60-70 characters.

Newsgroups still don't love long lines.
