I did have one cart monitor that had a picture, but flipping verticaly!
so, I noticed that the amp I had didn't work right for a stronger signal, but.....the AW pinout only puts out a comp sync from pin 13....
which goes to horizontal sync on a vga plug.....
to get to the point.....this sync split WORKED!!!!!!!!
when I split it and had the vert running through pin 14, the picture stayed still!!!! a little off to the side on a monitor that doesn't have a screen adjust on it

only brightness and color...

yeah, it's old!
but, I don't freakin care!! I finally got the signal to come through!!!
