So im trying to find out if its possible to RGB mod this old PVM style monitor. The brain is a M52016SP. It has RGB out and a NTSC/video mode switch on pin 17 (I relize that a RGB mod might be impossible) But if i get A NTSC subcarrier xtal and make pin 17 switchable between 5v and ground. Might that do the trick for correct colour and sync on NTSC composite? Might it be possible to connect RGB on the outputs or atleast ground pin 17 and add a NTSC subcarrier xtal? Any help is welcome.
