So some updates on muh PVM 9L2. RGB is working but has some issues.

The termination is weird, it's directly before the gun driver circuitry(drives the base of a transistor that switches the 120V). I don't think its a standard RGB signal, it has a 0-5VDC digital clock on each color channel, with the analog RGB image 0.7VDC on top of that. Just putting the Saturns signal in directly works but whites become red if they cover a large area of the screen. Also terminating to 75Ohms will blank the display, this link is very high impedance.

Whats more is the sync is not very reliable. I'm using the composite out, when its in the composite socket I get a clean sync but a double image since its showing both inputs. Putting it in the external sync port it jumps around and has interference throughout the frame.
