JROK's are used to convert RGB to Composite or SVIDEO signals.

Here's their product info

Edit: Added

What does it do ?

This unit will convert the Red, Green and Blue video signals coming out of a video game and convert it into the composite NTSC video, or S-Video, output.

It allows you to plug a Video arcade game board into a regular TV receiver that accepts video, or S-Video input, in the NTSC encoding format.

This board ONLY works with standard resolution arcade boardsets ( 15kHz horizontal line frequency )

Hope this helps,

I would rather see something going the other way...

but that is what a ArcadeVGA is for... but I do love my 9700... but I guess I don't have a use for it on an arcade monitor.  I would love to see some game running at 8xAA at low resolutions..

J-ROC is commonly used by people that build superguns.

It allows you to connect any PCB/JAMMA board directly to your TV.

I have a converter that converts a composite signal to RGB.  I'm using it on a 50" rear projection monitor from a Konami Krypt Killer machine to use as a TV.  The picture isn't as good as a regular TV but running a digital set tob box to it makes it more than satisfactory for a cheap big screen TV.
