One of the guys on the coco list is making a scan doubler that takes RGB at
NTSC scan rates, and doubles the data rate, then doubles the line to be fed
to a vga monitor. It works quite well on my coco3. I have no idea if it
could be used on a PAL system or not.

Thanks for the pointer. I've heard of these scan doublers, it seems that such
a device is an interface for precisely this purpose. But I don't know can it
be bought in a store (or on the net somewhere) or it just exists as a
solder-it-yourself kit...
You can get commercial ones from various audiovisual equipment
manufacturers such as extron, altinex {maybe}, scan-do, sony {not sure
if the one I'm thinking of is still available}. Scalers would tend to
have extra capabilities you might not need.
