[Coco] display width of the coco3

[Frank Pittel]

When in character mode how many characters is a coco3 supposed to be
able to display on a line? When I hook the video output of my coco to
the video in on my tv I only get 32 characters across the screen.

Is there any adapters available to allow me to connect my coco3 to one
of the many svga monitors that I have?
