Techknight™ - SE/30 Greyscale MOD /w IIsi video card

Any r/l/c networks for the yoke would have to be changed to suit the freq. Maybe not within 10% though.

I do know the analog board wont do 640x480. I tried that and the horizontal linearity was way out and had barkhausen noise along with severe foldover.

The vertical, and crt modulation was fine. Its the horizontal deflection that became a problem

so are you pretty sure 512x384 is possible?

Only one way to find out...
