IIgs RGB to YPbPr Component experiment

["jsnospam@cimmeri.com" <js@cimmeri.com>]

Following up to earlier posts from Scott Alfter, Michael Mahon, and
myself, I went ahead and conducted further research on this subject.  I
found a solution that produces very nice results.  But nothing worth
having is free in this world.

1.  I obtained a very nicely crafted IIgs -> SCART cable from Roger
Johnstone (frequent poster here).

2.  From the U.K., I obtained a Keene Electronics Aptus1 SCART RGB ->
YPbPr conversion box.  Time is money to me and I didn't have time to
spend hours constructing something that would be functional but still
look like dog doo.

3.  Received both.  Plugged Roger's cable into my IIgs, then into the
Aptus1.   Used some cheapo component cables from the Aptus1 to my
Samsung 192MP 19" LCDTV 1280x1024 native resolution.

4.  Press "Source" button twice on the 192MP remote control, and I had
beautitful color RGB on my LCD.      Press Source twice more, back to
PC.

Time spent hooking up: 2 minutes.

See links for photos.  I had a hard time holding camera steady enough
for these... so any blurriness is from my photography, and the actual
vividness is better.    Interestingly, the HGR modes showed perfectly
solid colors, whereas the GSOS desktop showed intersticed black lines.
Probably has to do with the upconversion process.

Future tests:
- I plan to test with a 640x480 LCD EDTV to see if that produces better
640x200 displays.

- the Samsung 910MP seems to come with a SCART connector already built
in, thus saving you having to buy an APTUS1 and a more tidy cable
situation.  I have not tried this option but I might.
