Arcade bods help, GBS-8220 RGB VGA Converter thing

[vanpeebles]

Are any of you arcade bods using a GBS-8220 CGA/EGA/YUV to VGA Arcade HD-Converter PCB (GBS-8220) board at all? I'm getting one to try with a QL and just wondered what the polarity and tip size was on the 5v in socket.

Any other tips would be great too!
