Just need to get the "real" X server working on mac68k, instead of the old 1-bit or OSFA color ones we have now. IIRC, there was a spurt of work last(?) year with the mac68k framebuffer that looked promising. Dunno what happened with that.
I currently don't have any 68k NB boxes (with the AV SCSI issues, I retired my Q840), but as soon as I get my CC operational again, that's what I'll be running on it.
