[Coco] [Color Computer] Re: TRS-80 CoCo Group Color Computer Composite Video - Compared

[Neil Morrison]

The 'switch box' contains a balun, a transformer for 75 to 300 ohms so
you can connect to the double screw terminals. However most all TVs
now have a 75 ohm in connector. In the USA it's called an F connector.
The Coco connects directly to that.
