IIgs RGB to VGA continued

This is a repost to restart a topic to earlier topics I'd been working
on of:

"IIgs RGB to YPbPr Component experiment"
and
"IIgs RGB to VGA experiment"


A few days ago, I received from Highway Games their #100 SCART RGB->VGA
converter.

http://www.converters.tv/products/converters/rgb_converters/100.html

I hadn't any luck with their #41 CGA(RBG)->VGA unit, so tried this
model as a replacement.

The #100 unit is a fully finished product w/ enclosure, worldwide AC
adapter, and some cables.   You would still need to supply a IIgs->
SCART cable.   It has an OSD menu where you can adjust output
resolution and other variables.

Accordingly, price is also much higher at $195 USD prior to shipping.
Still a cheaper, more flexible, and possibly longer-lived option than
an LCDTV, though.

I tested with both a Sony 17" CPDE200 VGA CRT and a Samsung 19" 910MP
LCD.   Results were very good with the CRT; even better with the LCD
(perhaps due to processing unique within the LCD).  Of most interest is
that color dithering (eg. in 640x200 mode) is intact, and backgrounds
(eg. Karateka) are solid colors.  Images are rock stable.

Will post photos here later.

In other news, I am also testing a lower cost, prototype unit for
RGB->VGA conversion using the Averlogic chipsets.  Results here also
look promising so far in all modes up to 320x200.   Still having
trouble with 640x200.
