Give me a quick BASIC program to demo the color/hires effects that
sucked on the hardware you've tried and I'll take a video of the
result. I'll see if I can get a good pic of my monitor with Appleworks
on it, but it's hard to take good photos of white text on a black
background.

In the default configuration I noticed some _horizontal_ artifacts on
single pixels in 80-col mode (e.g. the point in a curly bracket). I
adjusted a couple of the OSD parameters and that went away.

I get the very best results for 80-column text by tinkering with the
sharpness setting of the converter, and putting it in S-video mode
(i.e. making it think the chroma is coming in on a separate connector,
which isn't in fact connected to anything). The only thing I could
wish for is green screen mode (yeah, I could disconnect the r,b lines
to the monitor but that's a bit extreme :)

But the difference between the s-video setting and regular color-
capable composite setting is just a matter of blur, not crawling or
other mobile artifacting.

I am using this converter: KWorld TV Box 1440. <http://

on eBay for around $40 a year or two ago.
