I've just merged support for a pretty simple monitor based machine from the DDR.
It's got plenty of memory (58k), supports a 64x24 line console and some super-lores graphics (64x24) and well, that's pretty much it.

I'm planning on adding the related Hübler Grafik MC which with hires graphics is probably slightly more interesting.
