[Coco] Re: again: CoCo RGB to VGA conversion

[Charlie]

Just for fun, I hooked one of my coco machines up to a VGA monitor using its
composite video out and an AVER media device. The device lets you plug
composite, S-video and has an RF tuner. It is in no way a "high-end" device.

The coco display looked blocky, but not bad at all. However, the 80 collum
text screen was no more readable than if the coco was plugged directly into
a TV using the composite output.
