        Todd, seems you never did any RGB interfacing at all! Do it this way:=
 Since it came from a CASIO tv, it should be a CGA type of video (15.750=
 KHz). Get ArcadeOS in www.arcadeos.com and configure it to run in an=
 arcade type monitor. It will make your PC run VGA in 15.750 KHz horizontal=
 frequency. Just tie togheter the 2 sync wires (h and v) and connect to=
 your small RGB panel. Of course you can use an old arcade board or a CGA=
 board without any changes. This "one pin" of sync is nothing more than=
 composite sync - H and V sync togheter.
