Wow, a version without connectors would cost just a few bucks to make up. Pretty simple design.

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.
