I am looking to buy/construct an encoder capable of taking RGB from a JAMMA based arcade board (15kHz R, G, B, comp-sync & GND) to PAL composite or s-video for display on a standard TV with these inputs. This is similar to a board made by JROK and sold in the US. Essentially, it consists of a single IC (Analog Devices AD725: RGB to NTSC/ PAL Encoder or similar) and a few other minor components.
I am looking for anyone in NZ that has knowledge about this type of converter or where i can source the IC at a reasonable price (i.e. not specifically shipped from outside of NZ).
The other alernative is to feed the RGB straight into the guns in the TV box, but i am still wary of this approach (would rather start with non-descruction approach).
Any help well recieved.
