Title: How to convert 15KHz RGB signal to composite?
Post by: punkysuen on December 27, 2021, 02:45:39 am

I am successful to install CRT_emudriver and have everything works fine through RGB input on PVM.
However, I want to try to make the picture more like what I have played in childhood, at the time I used composite.
I have followed some VGA to composite scheme on the internet, but failed.
Does anyone did the similar thing successfully?

Adjust the focus knob on the flyback to be slightly off?

I can't believe that, back in the early 1980's, I used to use a TRS-80 clone and a 13" B&W TV with RF input as a monitor. Glad to have moved on.
