This makes me think back: Around 2005 I wanted to drive XY displays with my PC and realized I had a DAC that was already driving at MHz rates: my VGA card. Of course, the blanking interval would always jerk the coordinates down to (0,0). So among my tricks was setting unreasonable video modes with the most horizontal pixels the CRTC would allow and as few lines as needed for the game's display.
It was pretty neat to be able to run MAME vector games on a proper display, with nothing more than a standard PC and a good analog scope, even if the display was never as crisp as the real thing.
