Btw, looking at the small number of chips and the ls257, that reminds me how I built hires into my selfbuilt pet replica - I used an ls257 to map the two lowest charrom address lines (char row select from the crtc) on top of the crtc memory address lines and a "pass through" character set... resulted in a weird memory layout though. That brings me to the question - what is the memory layout of the hires mode? That should give us some more hints...
