Hi to everybody,
I need to connect a GBS-8220 RGB to VGA converter (http://www.jammaboards.com/store/rgb-cga-ega-yuv-to-vga-converter-pcb-gbs-8220/prod_291.html) to a very old home computer (Sinclair QL).
The converter only accept (PAL) 60 Hz Vsync frequency and the computer only give (PAL) 50 Hz.
So, my idea is to modify the Vsync frequency from the computer in order to input 60Hz to the converter.
(see the enclosure)
Maybe it is a stupid idea... do you think it would be possible?
Thanks a lot
