Never got round to using this card, time to clean house. I hooked it up once to make sure it worked and it's been in its bubble wrap packaging since.
Looking for $40 shipped. Comes with a 5 Pin RGB Cable and a 2-pin Power Cable
Thanks

The VGA to RGB CGA Converter can convert a VGA signal to CGA signal. This allows you to play high resolution 31k arcade games on a CGA CRT monitor (15k) or any TV monitor (using AV/RCA or svideo connection, can accept both PAL and NTSC outout). With the help of this converter, you do not need to upgrade the monitor of your old arcade cabinet specially for new arcade games. Furthermore, You can use the VGA input of the Converter to play PC games on a CGA CRT / TV Monitor. That means you can build your own computer-based arcade machine easily.
