No, its an rf output, designed to be fed to a std ntsc tv, and I believe 
selectable to be on either channel 3 or channel 4.  I've found the cheap 9" 
B&W tvs of 15 years ago to be quite usable.  Colors tv's too, but my main 
interest was programming so text was important & the colors detract from 
that.

There are, or were, little adapter switches that had a transformer in them 
for the coco's output, adapting its 75 ohm coax to the 300 ohm flat line 
used by most tv's 20 years ago.  It also supplied the FCC required 
isolation to keep the coco's signal from bothering the neighbors tv's.

There were also, video kits made to get a composite output, one of my 
coco's has one in it.

Cheers, gene
