What is the Switch-a-roo?

The Switch-a-roo is a  video cable that will allow you to use a Tandy Color Computer 3 on a modern display (HDMI or DVI) in either RGB or composite mode.

What else will I need with the Switch-a-roo ?

Well besides a Coco3 and your display  you will need a SCART to HDMI converter. Here is an interesting article on SCART to HDMI converters to avoid.

Also you will need a HDMI cable (or HDMI to DVI cable if using a DVI display) and finally a USB power source (any USB power source will do even the 1 amp ones).

What is the switch for?

The switch allows you to easily switch between RGB and Composite modes. This allows you to go from displaying the Coco3’s crisp RGB video to  PMODE 4 Artifact Colors without having to swap cables or displays. (Please note that PMODE 4 Artifact colors are only available on NTSC systems.)

What is the USB cable for?

The USB cable needs plugged into  5 volt USB power source (not included). It is needed for the SCART to HDMI converter box.
