Amiga RGB to YPrPb - where can I get it?

One problem with that design. Pin 21 on the video port is not -5v on all Amigas.

Not sure that I'm qualified to say, but it doesn't appear that -5V is actually required for that circuit to work. Perhaps someone that has actual EE chops can say.

The OP amps use +5 and -5 volts.

Hmm, not saying that you're incorrect, but where on the schematic is that shown? Totally not seeing any connection from -5V or VEE to any opamp.

The power connections for the OP amps aren't shown on the schematic.

Pin 8 is V+ and pin 4 is V-.
