Dartstars are quite reliable and was the first coin operated dart game to generate color video graphics. If you connect to the RCA video output jack on the gameboard, you can feed it to the standard video input to a tv set or VCR.
Set a dip switch and move a jumper on the board and it puts out a full color video signal.
Plus, via dip switch settings, you could use any one of three different dart game manufacturer's target heads: Arachnid, Merit, or Valley.
It also uses a conventional "Peter Chou" screw terminal power supply like a modern video arcade game does.
