@foone It depends on the video mode it expects. A VGA card should probably be able to drive it, but if it wants composite video style timing (525 or 625 lines), you'll probably need a sync separator and a composite source.
edit: I think there's a way to hook a Pi up to generate VGA using an R2R DAC, but it's been ages since I looked. It has a parallel output too, on the GPIOs, it's meant for LCDs. I have no idea how to set the mode timing though.
