[Coco] coco 3 composite output

[Didier Derny]

not compared to another coco 3  but to a coco 2 using a composite interface
the coco 2 screen is perfectly readable

coco 3 in 80 cols in unreadable   something like if odd or even columns 
missing in the caracters
coco 3 in 40 cols not so good but usable
coco 3 in 32 cols bearly usable   ( for example unable to see the 
difference  between 8 and S )

I'll try to make some photographs but the result is generally quite 
different of what I see on the screen
(generally looks better)
