[Coco] Re: S-video Prospects...

[Stephen H. Fischer]

Hi,

Well it has been more than 25 years since I have been in Chicago.

>From the SVGA monitor reference, please read another message
that was just posted.

S-Video is a totatly different method of displaying video from the CoCo 3.

The $15 is an estimate for parts for a home built project for those persons 
who can build their own.

If persons cannot build their own, maybe they can get someone to build a 
"lump" in a cable version that would just plug into the CoCo 3 and their 
S-Video NTSC TV.

Which one you want is dependent on if you have a Computer Monitor or a NTSC 
TV with a S-Video input.

Look for another tree.
