It's the AL-250 chip. Look up the datasheet. It's not just a line-doubler, it handles the PAL to VGA conversion just like it handles the RGB to VGA.

I fail to see then how, without a frame buffer, you can display a 50Hz PAL output on a VGA monitor that syncs at 60Hz. I'm sure it won't.
FWIW I have an old COMPAQ SVGA monitor that _will_ sync at 50Hz. But it's not common.
